I hope it is ok to mention this here. I didn't see any harm in doing do so.
PlanetMGC (www.planetmgc.com) is a gaming community mainly for UK gamers over 25 years of age. I am just a normal member but am so impressed with the site that I wanted to pass on its details to you. PS3 games are regularly organised for RFOM, Motorstorm, F1 among others and members are welcome to add their own sessions to the calendar for any games.
If you are based in the UK and are over 25 years of age then why not come and have a look at www.planetmgc.com and join the forums.
