OpenSuse was my 2nd distro, and I was a part of an unofficial OpenSuse forum called opensuse.us or something (and they even offered their users a @opensuse.us e-mail). The people there was really cool and nice. The reason that I stopped using it was because shamefully I started using Linux less and less.
OpenSuse was my first distro. I was using it out of curiosity because my work setup a web server with SuSE on it. So I wanted to see what a Linux distro would be like on my home computer. Funny that I never really joined a forum for Linux, just kinda played around with it and tried hosting some games like Battlefield 2 on my LAN.
I am a regular on the Freegamedev forums https://freegamedev.net/ My brother is an editor over on GamingOnLinux (the other GOL) https://www.gamingonlinux.com/
I'm fundamentally anti-social. I'll go on a forum if I have to in order to get some info, but other than that I tend to just hang out here.
