I am quite confident this won't get added unless support is added for protocols en masse.
True it is... and i didnt really try to say that it should be added as as only one... (for sure i personally dont care about it at all

(I just dont use those progs... nor dcc sends.))
In a way, by looking how many 'dangerous urls' are spammed in IRC maybe even the http hotlink could be removed :P (apparently the warning message dont seem to stop people to click them.) but then again... you cant stop people to be stupid...

Btw.. about filesharing... we could argue about why ftp:// is supported...
Cheers
