Plan a Friendsgiving Potluck Sign Up Sheet So Nobody Brings the Same Dish

You are a relaxed, organized party host who plans potlucks that end up balanced instead of five bowls of mashed potatoes and no main dish. I am hosting a Friendsgiving and want a clear sign up sheet plus a short message to my guests. Use only the details I give you. Do not invent guest names, dietary needs, or dishes people already promised. If something is missing, mark it [NEEDS INPUT].

Date, start time, and location type (apartment, house, backyard, shared office space): [EVENT]
Number of guests and any kids: [GUESTS]
What I am cooking or providing myself (main dish, drinks, plates, nothing yet): [HOST PROVIDES]
Known dietary needs and allergies among guests: [DIETS]
Kitchen limits (oven space, fridge space, number of burners, no microwave): [KITCHEN]
Where the sign up will live (shared spreadsheet, group chat list, printed sheet, sign up app): [FORMAT]
Budget expectations or a "bring what you can" note: [BUDGET NOTE]

Requirements:
1. Calculate a balanced dish mix for [GUESTS]: mains, sides, salads or vegetables, breads, desserts, drinks, and non food items (ice, plates, containers for leftovers). Show how many slots each category needs and subtract what [HOST PROVIDES] already covers.
2. Build the sign up sheet as a table with category, slot number, suggested dish idea, serves about, dietary label, and a blank name column. Keep dish ideas as suggestions, not assignments.
3. Make sure [DIETS] are covered by at least one main and two sides that everyone can eat. Add a simple labeling rule so guests mark common allergens on their dish.
4. Respect [KITCHEN]: mark which slots should arrive ready to serve or need no oven, and add a reheating schedule if oven time is limited.
5. Add a rule that blocks duplicates in [FORMAT], such as one name per slot and a note to check before adding a new dish.
6. Write a warm, short group message under 120 words that shares [EVENT], the sign up link or place, a sign up deadline, and [BUDGET NOTE] without sounding bossy.
7. Write a friendly reminder message for three days before the event that nudges empty slots.
8. Add a leftovers plan: containers, who takes what, and a reminder to refrigerate food within two hours.

Deliverables:
1. Dish mix calculation
2. Ready to copy sign up sheet table
3. Diet coverage check and kitchen timing notes
4. Invite message and reminder message
5. Leftovers plan and a list of [NEEDS INPUT] questions
