ill try it, thanks.
"use at your own risk" you mean it may be buggy or something else?
I think he meant that it's an unoffical app and if the creator wanted, nothing would stop him from stealing your login details (that is if you login on the app). Bitcointalk doesn't have an API (yet; the requirements for the new forum seem to spell this one out pretty clearly) and / or an OAuth endpoint that would allow for limited access to the account and thus the only way to login to Bitcointalk in external software is via a session cookie (temporary, not user friendly, still pretty unsafe) or typing in your login details (extremely unsafe, possibly gives full control over your account to the other person).
Then again, considering the fact that theymos just recently added ReCaptcha to the login procedure and, according to other users, the app is no longer being actively updated, guess trying to login would be pointless as well.
