Some games just don't show up in search, making it impossible to add them to a list. One such game is Ratchet and Clank Future: Tools of Destruction.
Also, the forums in general have been messed up lately. Don't think I've seen too much about this. A lot of responses are either not notified or are notified late and the main forum page seems to have a delayed update time rather than immediate.
