Honestly, there are so many legit reasons why I'm sticking to 6.03 too. I think 5.61 was the peak until 5.91 or so. Then I think 5.91 was the peak until 6.03. And I think 6.03 is going to be the best (in my humble opinion) unless the nick sort list thing is changed, among a lot of other complaints.

But in the end, if mIRC were never created in the first place, IRC wouldn't be what it is today I bet. I.E. less newbies for one.
