well.. it would be possible to get some beta support working with the current build of Bit Che, but it wouldnt be perfect..
Problem#1:
a. you could use the "special.exe" login tool (copy the script header block from Oink.Me.Uk's).. this will use Internet Explorer to login and then your forums cookies will be saved into Bit Che after logging in. you will have to repeat this everytime the cookie expires though.
b. a little more work, but should be more stable, use a web page to calculate the md5 hash of your login and enter this into Bit Che. (since the md5 never changes, as long as you caluclate hash for the right string, Bit Che should be able to automatically login whenever with that).
Problem #2:
it is not going to be possible to fetch the torrent out of the thread's post, simply because the forums uses different numbers.. BUT you could just simply use the torrents page for both the page and the .torrent file, and then just manually open the web page to download a torrent if you find one on that forum you really want... its not perfect, but it would work
Problem #3:
looks like the forums search function requires image verification.. does this go away once you login with an account?
