I have no idea how to do anything on fanpop now... I think the new fanpop sucks!

I am pretty sure u were here after the "im" left man. And I think we've already came to the conclusion that fanpop mobile is not up to par. u can still post to a uithangbord if you're having some sort of problem take it up with the F4 rather than whining and complaining to us.

Well, fanpop mobile could use a little work, that's true.
The IM has been gone for a while, though I think they might possibly be working on a new one? I'm not sure. (I think that'd bring a lot of new people to the site, though)
As for posting on the uithangbord and making comments, that seems to be a problem with just your device, because it's working just fine for me.
Have u contacted the F4?

I mean, unless for some reason my account is really behind on updates, everything is working pretty much the same for me as they have been.

fanpop is a no no for you
let me just help u with that .....

If u are having trouble posting to someones uithangbord it could be one of both of the following:
1. The person's account is set up to only allow those that he / she has fanned. Try sending the person a message.
2. u are using IE. Try changing to FF of GC. I use FF.
