As someone who grew up on Windows + mIRC + vBulletin forums (late 90s, early 00s), mIRC will always ignite fond memories :)<p>For those who still use IRC, but maybe on other platforms than Windows, HexChat could be considered a spiritual successor to mIRC, but it's also open source and available on a ton of platforms. Just a happy user here, not affiliated in any way.<p>Edit: Hm, seems it was some time ago I checked out the news/blog of HexChat, seems like last version was a year ago. I still use it without problems, but maybe people could share any active forks if they know about them?
