I don't think it needs much explaining I just thought it would be useful to have a hatbox in the corner sort of like facebook but less crowded so people who don't use t on't be bothered. My reason for this is sometimes I'm talking to people and then I get into writing a post for an rp and that may take up to half an hour or more occasionally if it's long post and I do lot of revising. By then people who had questions or just said hi on my "wall" have logged off without a word back from me.
I get some people wouldn't want this so a setting to hide it or cut it off would also be needed. Just thought I'd throw it out there.
