There are a number of other features and services, including web e-mail and URL redirection. This site contains info on many clients and aspects of IRC, but does have a small selection of mIRC scripts. The site feels a bit disorganized but if you want a variety of information, it may be just what you are looking for. The site looks nice though. This site has a large archive of scripts.
Users can leave comments on scripts, as well as on the web board.
Com Nice looking site with tons of scripts. Scripts are NOT reviewed or rated in any way, but you will be able to find scripts and addons going back as far as mIRC 4.7. Unfortuantely, scripts here tend to come with tons of external programs and extra files no one needs, but you may find some interesting stuff. Also has an archive of older mIRC versions and some other stuff. You can also find other info on mIRC, eggdrop files, and a chat room.
