I think one of them would be assuming how the system works. I'll admit that I've joined a lot of BTC sites not reading the rules. This time I read rules joining this new site.
Which other sites did you join? I've been meaning to get more BTC related sites to join.
Reddit, and Bitcoin Italia. I'm sure that you've heard of these ones. It's not as great as this forum anyway. I'm upset that I hadn't joined earlier.
