[quote=@pugbutter][@NuttsnBolts] But you're describing a length ceiling, a maximum post length, and I'm 99% sure this doesn't exist anywhere in the Guild. No one is [i]forcing[/i] you to write short posts if you RP in Casual or Free, so that logic doesn't fly.[/quote]
No, but you're still likely to get a short post in return, which he just established he doesn't want. The Advanced section isn't defined by posting length (at least it shouldn't be), but it is statistically much more likely for long posts to occur. Ergo, if you like posts of great length and depth, why gamble by going to the casual section? The logic seems solid to me.

Anyways, putting "no one-liners" on your profile or interest check seems fine to me. You're just communicating what you're looking for. It's a way for the poster to attract the partners they want, and for the people browsing to determine whether this poster is a good partner for them. It only becomes a problem if you act snobby about it, or you enforce it with a zero-tolerance policy.
