I play online regularly and new players are always welcome. There are regular games each weekend on the Artemis Teamspeak server.

People use the Friday Night Flights thread, Saturday Night Flights thread, Sunday Night Flights thread and Game On? thread to say when they are online and organise games. These are casual games and anyone is welcome to come along and play.
I also run an RP community that you are welcome to join. We follow standard procedures and protocols, have a full rank structure and promotions, train together, and play in role as Officers of the TSN. All the details can be found on the wiki. The RP group runs every Saturday night for about 3 hours, from 8:30pm UTC onwards. Full details of the RP community can be found in the RP Community Handbook, created for new members and current players of the community.
