[Solved] Way to back up Private Messages?

[Ryudo]

I'm running out of space for my PMs, in fact I'm at 98%~100% now. Is there a way to maybe Archive them where they don't take space? A lot of these PMs are worth keeping sadly, so I don't want to delete them. I could of course opt to download each message in a separate HTML file, but that's a bit time consuming..

[Edit]

Apparently there's a Download Message button on the Inbox page... I'm blind for not having noticed this before. Sorry guys!
