Unclear On The Difference Between Freeform Group And Open RP

[Red-Scarlet]

See title. I'm not 100% clear on what the distinction is between those two.

Follow-up question, if I have a Role Play request that can fit into both Freeform Group/Open RP and Non-Binary, am I allowed to post it in both?

Thank you for the knowledge. I thought it was something like that, but wasn't wholly sure, so I'm glad to get clarity.
