Like a lot of people here it seems, I used to visit MyBB, and usually check out the gaming section there, then when they announced MyGaming, I signed up here rather. I did lurk for quite a while though, just checking out the articles, and poking around in the forums but not really posting. I think I really started getting involved when I won a competition "whistling:
I think it was Dead Space 2 that I won. I wasn't active enough on the forum to enter here, but I got an entry on Facebook. I did get trolled a bit when I was surprised to have actually won.
I've stuck around because I've come to enjoy being part of the community and chatting about gaming or whatever else comes up with the nice folks here. There are always interesting conversations going on, and it's lekker to be involved. The awesome competitions are a nice bonus though.
