Well their reasoning for it making mIRC worse is that IM's support this feature already, which is beside the point completely.
well, how much more benefitial would v/v to mirc?? outside of being a novelty, would it actually help mirc or irc users (i don't know), would it hurt (i can't really say)... one this has become clear... the fact that some want v/v supported and some don't.. given that wouldn't it stand to reason to maybe introduce it as a plugin as mIRCManiac had suggested? then if the demand/usage increases then it could be considered to incorporate it in mirc.. imo opinion it would be a satisfactory call for everyone(fore and against)..
