If by "not showing up" you mean it's not in the game tracker, there are a couple possible reasons.
1) You're using the same port to host the server and run the client. Simple fix: Start your server, then start RF Launcher again, specify a new port in settings and run like normal.
2) You're router ports aren't forwarded (assuming you're using a router). Not so simple fix, check http://www.portforward.com/ for specifics.
Well since ghostkid has dropped the server. I'll fire up my Red Storm Modification server. It's DM and hopefully you have the maps. Click on my signature to see what map is currently running. There are defaults in the mix. So far I am playing with XENON and the weapons do rock.
<--Gatling Gun noob. I have to warn you guys, the gun empties the 100 round clip in less than 3 seconds.
