Single post in Move Posts in Forums

I'm not sure if anyone posted about this before, but I didn't see anything about it. I'm not sure if you could just pm a mod to have them move a post in a thread, or if you could even do that, but yeah. Anyway, I made a large shop for example. After the fact, People have asked if they can join, and I'd like to allow them to join, but the shop has been open for awhile, and many have posted, which would seperate them from the rest of the shop owners. Maybe we could make a way to move posts, so that people could move things around, to join shops after the fact. I'm not sure if there would be any issues with this, but please, let me know. I'm curious if this could be a possibility, but if not, I understand. Hopefully this makes sense, I'm a bit tired while writing this XD
