Welcome to "our" family!
Group builds are just a bunch of members that get together with a common theme for a build. You can see how varied they are by looking at the subjects at the top of the forum. Someone in the group sets up a topic and asks for the administrator (Lawrence Hansen) to make it a stickey (meaning it stays at the top of the topic list). Then everyone in the build posts their progress, problems, questions, pictures, etc. to that topic. Everyone is free to join. You just post into the topic that you'd like to join. They have a start date and a finish date. These are the "official" dates of the build, but no one's going to say anything if you start a little early or go late. It's all for fun and learning.
There is quite a discussion going on right now on how the group builds should be handled in the future. You might want to open that topic and scan through what's been said.
And NEVER be sorry about asking a question. That's why were all members to ask and learn. At least for me, what help I can offer back is only a partial repayment for all the advice, help, and friendship I've been given on this forum.
