As has been said, I don't have an objection to mIRC supporting some sort of feature whereby you can specify a protocol and a program as links, or if it supports every protocol (though how mIRC would define between iuergheiu:// and <realprotocol>:// I don't know).

I do have an objection to mIRC solely adding support for such protocols as "ed2k://" or "dchub://", and I have explained why.

I agree with both these comments.
