MSN Groups, Now Multiply Apparently Has Glitches

Well the last new post you can ignore. I have a group on MSN and they are shutting groups down as of February so I am moving everything over to their new site Multipy. It had an option to add my RSS feed over there from my blog. I thought that was really nice until I realized that the post I made to my group over THERE somehow made it's way over here to my blog. I can't even begin to understand that one. =/
