>mIRC already has one perfectly acceptable method of transferring files, which is used by every IRC client that I've used. Why waste more effort when the functionality to send files already exists?

Duh, DCC SEND is not perfect! I think it's the most stupid protocol there is.

Yeah, sure. Kazaa is only made for file swapping - mIRC is not. So, i can't see how it could get a wrose rep. than Kazaa. It isn't even the same type of software.
And the best thing with IRC is that you can easily stay away from things you don't want to take part of. You could easily stay away from this too. Or are you afraid that the feds are going to take mIRC away from you? It's never going to happen. They can't make every app, that can send files, illegal. Should file transfers in your browser/ftp client also be slower than they have to be, to stop people from sharing warez and stuff? Where is the logic?
