I really don't know of a certain time. Felix is relatively new and he's signed up. You have about the same posts as he does. You can join, too. Just be sure you can do it before you do. The reason we want people that have been here a bit is because we want to make sure you can be trusted. It's just that we don't want someone that's just joined and then will not follow through with the promise to send cards. A lot of people join and then never come back after making a couple of replies. I hope I've explained that well.
