"TBA" in an exchange request body on the AO3...?

I poked through the early sign-ups for the everywoman '22 exchange, and I saw a fair percentage that had selected the fandom and characters, but said only "TBA" in the request body.

Is that a normal and acceptable thing? Could I put in all my requests now, so that people know, and then go back and fill them in later? (There's no chance of getting accidentally trapped into a blank request, unless I lose all internet access between now and the end of sign-ups?)

Dear Everywoman Author (2022)

Dear Everywoman Author:

Hi! Thank you for sharing these fandoms and loving their female characters! I’m sure that whatever you most want to celebrate in these characters and their worlds will make a lovely story! If you’d like more story thoughts from me, read on.

Across fandoms

I usually most enjoy stories with the feel of canon, whether an incident or interlude that could have been there all along, or a different choice or chance that diverges from canon to somewhere new. To engage me with a full-on (not divergent) AU, a good tactic is to play up where the original themes thrive in the new concept.

With a few specific exceptions, I usually prefer gen to romance. Mystery, drama, history, reflection, confrontation, growth, discovery, tragedy! The quiet times between adventures! For romance, I have fairly vanilla tastes. I value fidelity, mutuality, and complementarity. Except for Journey to the West, which is a comedy, I do opt in for tragedy, including requested character death; I like stories of continuing on from bereavement.

Where appropriate, I especially love bits where heroes incidentally, without thinking they’re doing anything special, show that they value others highly — that is, not only their own loved ones, but the dignity and abundant life of all people, especially those on the margins.

Please do mix and match the requested characters with each other and added appropriate characters to build your story as you need! Please don't feel confined to "solo introspection" for characters requested outside pairs and groups.

Do Not Want (DNW)

Thank you for taking these into consideration; I appreciate it!

Villains should do villainy, of course, and that can make awesome stories! But when villains win, I feel that it's properly a tragedy, not a triumph; please don't ask me to root for evil. Also, no second-person, please (unless you're crafting something super clever).

Thank you very much!
