Why can't we add pictures and where do I upload my avatar?
I think that custom avatars are a Subscriber privilege only, and I have the idea that pics are mostly frowned upon because they make the forum so slow to load for some people. Pics can be linked to from a flickr or photobucket account, and Subscribers can add attachments to their posts.
Subscription really isn't that expensive, particularly for US citizens, and it does help to keep this wonderful community going. I would pay a lot more to be a Sub if I had to, and donate Subscriptions when I can.
