Pie Baking Contest RSVP Website: Entry Slots, an Oven Window, and a Category Cap
A pie baking contest RSVP has to lock an entry slot and an oven window before the ovens are scheduled, because a maybe does not hold an oven window.

A pie contest breaks when the hall has four ovens and eleven bakers expect a slot, or when the fruit category was capped at eight pies and twelve fruit pies show up while the custard table is empty. Oven time, category, and the number of entries are set before the first tin goes in. The kitchen does not add an oven because a neighbor decided to bake after the schedule was posted. A maybe does not hold an oven window.
You can create a pie baking contest RSVP that fills the oven windows the hall can run, caps each category, and separates the person baking from the people who only come to taste.
Ask what this kitchen can bake
Walk the hall or call the host before you send the link. Write down how many ovens work, which ones run at the temperature you need, how many racks are trustworthy, how long a pie in your contest is allowed to bake, and how many cooling racks you have. Those numbers are your cap.
An oven window is one pie, one baker, one block of time. Two pies from one person are two windows if they cannot go in together. Say whether a baker may enter one pie or two. Ask whether people bake on site or bring a finished pie. If this contest uses the hall ovens, the RSVP is for windows. If pies arrive finished, do not pretend there is an oven schedule. Pick the one you are running and write it on the page.
This page assumes bakers use the hall ovens. Ask the last time you can change the schedule without leaving an oven cold or double-booked. If a no-show after that time still blocks a window someone else could have used, print that rule. Ask where tins and fillings come from. If bakers bring filling and you supply tins, say that. If they bring everything but the oven, say that too.
Set a capacity limit on pies in the ovens, not on relatives who want to watch. When the last window is taken, the form should say the ovens are full. A baker who might come still needs a rack and a block of time. If the schedule is full, they are not in this contest.
Categories and who is actually baking
Judges need a balanced table, and the oven schedule needs to know which pies must be watched. Ask each baker to put the pie in one category you defined, with a cap on each:
Fruit means a fruit filling, capped at the number of windows you assigned to fruit
Custard or cream means a pie that has to cool under the rule you print, with its own cap
Savory means a pie that is not a dessert, with its own cap, and only if you are judging that category
Close a category when its cap is hit even if another category still has room. Say that on the form. A baker who will not pick a category does not get a window. Ask them to name the pie in a few words so the judge's sheet matches the tin, including nuts in the crust or alcohol in a filling. You are not collecting a full recipe.
A second baker in the same house is a second entry. They get a window only if one remains. One form that hides an extra baker puts two people on one rack. Relatives who ride along are not entries unless they submit their own pie.
Tasters are a second list
People who come to eat are not bakers. If the hall caps chairs or plates, set that number separately. Collect dietary limits for tasters only where it changes what you serve them: a nut allergy that means they cannot take a slice from a shared nut crust, or a need to avoid gluten if you did not label those pies. Severity matters. A dislike of raisin is not the same as a nut allergy at a cutting table. Label pies from the baker's note. Do not promise a separate pie you did not schedule.
Collect arrival windows for bakers. Oven time only works if the person is there when the window starts. Offer real blocks, such as 9:00, 10:00, and 11:00, and cap each block at the number of ovens. A baker who misses the start of a window does not get the next baker's rack. Put the minutes you will hold a window before you release it to a standby.
The minute the ovens are scheduled
The meeting point is the kitchen door, not the dining room. Put the address, where to park, and which door is unlocked for bakers on the page. Tasters use the hall door at the time you set for judging, which is after the last window plus the cooling time you wrote down. Do not invite tasters for the moment the first pie goes in.
Tie your RSVP deadline to the hour you post the oven schedule. After that, a late yes is a call about a cancellation, not a promise of another rack. If you want names ready when someone drops, keep them as standbys in a named category and tell them they do not have a window until you write back. A maybe does not hold an oven window.
Export the list the day you lock: baker or not, category, pie note for the label, oven window, taster count, dietary line for tasters, and phone. A pie baking contest RSVP is finished when every window has one pie, every category is inside its cap, and the kitchen can turn the ovens on without rebuilding your schedule at the door.
