Can like, a mod go through my pms and delete like everything thats not been active in the last month and a half please? Since I'm only down to 75 percent...
Delete in bulk. Make an adventure out of it. That way you can go through everything and keep what you want... it may take a long time, but you let them get out of control. I always keep my messages nice and trimmed.
You should have checkboxes on the messages, and you can just check the ones you don't want, and then delete them all in one lump. I do it every so often
