Has he made a lot of replies on the current boards? nope, but he HAS replied. One example: here
Surely you cant think that every suggestion made here can/will be implemented, or be put in the very next version? You want examples of those that have, multiserver, IRCX events, changes in perform pop to mind.
Just because Khaled doesnt reply to each and every post, (or even tons of them) doesnt mean he doesnt read them or give them (and the literally thousands of emails he gets daily )consideration. One of the reasons for having a feature suggestion area is so that ppl can post their suggestions and others can comment, which then gives ideas for the future. Course, thats not counting feature requests made for things that are ALREADY
in mIRC, but ppl didnt bother to look, or bugs that are in fact NOT bugs (again, because ppl didnt read). That he and Tjerk created this forum should be an idication that input is wanted, and i can assure you that input matters. If you think he doesnt "react" take a look at versions.txt
for any release.
