Hello Toast, nice to see you and thanks for taking an interest in wanting to join the Clan
First thing to do is join our Steam Community Group here
http://steamcommunity.com/groups/WDGcommunityThis will keep you informed about what's happening in the community
Secondly, get involved! Although we're listed as a TF2 clan, we are actually more of a multi-gaming community now and we play other games too, so keep an eye on the forum, and join us for our TF2 Fragfest Fridays, our Llama Nights and for anything else that we do. Get involved on the forum too and post as a way of you getting to know us and us getting to know you.
You've said, you play Minecraft and MW2, are there any other games you're interested in?
Finally, we usually don't have people under the age of 18 joining the Clan (I've made this information easier to find in the Clan Recruitment post above). However as I've said, there is still plenty of opportunity to get involved in everything that's happening and you're welcome to jump on the TF2 servers at any time.
