The fact is that unreal ircd and unreal ircd spinoffs sucks. All they are is a bunch of channel and user modes that no one ever uses
if you look it from creators view it doesnt suck, for difference of conference room that savent been changed for years, unreal in every version has some updates and new commands that are made to please certan users.
It is good to see that some ircd is advancing in every version on higher level, i am not shure that you can say this for CR
The fact is that it is easy to set up, so all the wannabe kiddy opers use it
maybe many users use it because it is free and already have services added, ppl can take any ircd but for 70% cases they would program own services and imo they dont have knowledge for it or it takes too long to make such things
