That isn't something mIRC has any control of. Sure, mIRC could automatically change your characters to all lowercase so that you don't have to think about it, but if someone makes a channel with uppercase, you wouldn't be able to join it. If it's such a problem, then tell anyone who makes a channel to use only lowercase.
But if we again take the channel #mirc as example, how would the owner of that channel feel if someone else registered the channel #mIRC, #miRC, #mirC. #Mirc, #MIrc, #MIRc, #mIRc, #MirC, #mIrC, #MiRc and #MIRC?
Doesn't it make sense that all spellings of a channelname goes to the same channel with the same users in it?
