Replacing user titles with Facebook-style "status"..
 

Eg, a user can just click on their own title and ajax-edit it.. and it starts with "is.."

Would look something like:

rnadmo
is: tired!

Editing only works on your own one, does nothing on other people's titles.

I don't want to use a mood mod, I want users to be able to type anything they want up to 'x' character limit (set in admincp or just pre-set in the hack)..

Anyone interested? or helping me on my way to doing it?

Sound's like a really good project hmm i could possibly help but i may not be experienced enough to do that .

You could edit the Mood HAck with the permission of the author

Doesn't it make more sense just to do a hack to the existing usertitle? The database entries are already there, all you'd need to do is modify the code for displaying the user title, to allow ajax-editing of that field.
