Lightbulb IM is a free XMPP client based partially on MeegIM (at the beggining, I just thought about porting it, but ended up rewriting and fixing and also breaking almost half of it, lol). Written using Qt and QtQuick, with qxmpp library. It’s in alpha stage, so bear in mind, that there might be bugs, crashes etc. Developed by: pisarz1958.
