We lost a lot of contact information when we switched from o3b.org to o3bclan.org, and again when we migrated the message board database. If you’re locked out of the board, it’s because old registrations were lost. Just drop Legion a line (send an email via the contact page) and he’ll set up a new registration for you so that you can gain full access to the site. Until then, you won’t be able to see anything but the Guest forum.
Unless your name is Glaser. Then you should crawl back under that rock.
