There aren't many.
Poetry shouldn't have limitations.
Here are my requests, though:
Please be literate. Most think this is a duh, but it's not.
When posting poetry, put a rating by the title. I know Gaia says nothing over PG13, but this is poetry, and it should be expressive like we need it to be. So no one is offended, put a rating.
When giving criticism, be nice and be constructive. I will be moderating, If I see an "It sucks", you will be kicked out of the guild. No ands, ifs, or buts. (or any other conjunction!!)
That's it.
I'll add more rules as I see fit.
