I'm not fond of novella posts, nor do I care for less than 100 word posts. A happy medium is what I'd like.
I want a site that's still relatively new so it's going to be easy for me to get acquainted with people – or a site that welcomes new members with open arms. No sites with strict cliques and people who only plot with people they already know, thank you.
The application shouldn't require me to list a bunch of nonessential stuff or details that aren't useful at the get-go – I want to get to know my character more as I write them.
Also, the site shouldn't turn away people whose native language isn't English, or people who wish to RP LGBTQIA+ individuals.
