Instead of a forum I thought it'd be great to jot down a few suggestions of alternatives to nibbling on forums, you might even get to make friends with new people and find out what they look like in real life.

Squash - A very invigorating sport and a great way to get sweaty with a friend. You're enclosed within walls so it's perfect stepping stone to the outside world.

A Pub Quiz - Gather all the people you know in real life, I believe four is usually required, and go to a public house on their quiz night. You'll be greeted by a wealth of knowledge, alcoholic beverages and actual facts, all under one roof, perfect.

Play Frisbee - An ideal summer afternoon activity, best in a local park. You can even intentionally throw it towards members of the opposite sex in order to approach them and strike up a conversation.

Ride a bicycle - They are such a versatile mode of transport and can be found in various forms. Suitable for all types of terrain, but make sure you get the right tool for the job, goodness, imagine if you turned up at a ramp park on a mountainbike.
