Ok, the messaging is the main problem I have with the for only sites. Of course that is their way to get you to pay money to be on here.
Click the little box next to the message you want to remove. Then, just after clicking there will be a little window that pops up on the bottom left side that will ask you what you want to do. There is a buttom there that will let you leave conversation.
It takes me a minute every time I have to remove messages. Pain in the ass.
That's another great thing about ebodies.org. No limit on messages.
