Welcome!
I'm still relatively new, but in just a few months I feel like I've been a member for years. Not experience-wise, but the amount of cool things I've learned since joining the site, if written down, would be quite a long list.
I started out just adding my collection to the site and occasionally posting in the forum. But nary a day goes by that I don't discover something new that I didn't realize was there before. And with each new thing, I got more and more involved, and at this point I feel I can confidently do anything on here. (Except a few things that my current state of permissions allow...and adding images since I don't yet have a scanner-but those will come with time)
Be sure to ask questions, we are all here to help!
