The ability to move/download/archive Threads/Channels between Servers by ALL USERS

I have a problem, and I think this idea is the solution:

I am an RPer on a couple of servers. I don't have admin status on the one I'd want to move the thread I'm active in from, but if the ability to be able to move, download or archive them if you're overly active in them or have the permissions to be in them.

This server that I'm on that I'm trapped on because I don't want to lose this thread is toxic. I don't want to be there anymore, but I don't want to leave and leave that thread; actually threads behind. If I could at least download or archive them it'd be better than nothing.

The server I would want to move them to is my own server. I don't want to be on the other server I'm on and want to bring them "Home" per se.

This would come in handy when you decide to break off from any server/channel what have you so that you can bring things with you. Also if you think you're going to get kicked for any reason and you want to save some of your lovely interactions or good memories then you'd be able to. 

One of these threads I'm thinking of has over 6k messages in it -- a little hard to just screenshot and repost... so... I think being able to move the whole thread from that server to my server would be the better option.

Thank you for your time!
