I think I can help with this, but first a little history. When we set up the forum, we made it so that a new person could register independently. The forum used a "captcha" security feature that after a while didn't work. We would get fifty to a hundred spam registrants a day. It was difficult sometimes to tell genuine ones from the fake, so we decided to register each one manually. That is a little onerous but actually saved quite a bit of time and is a simple "copy and paste" to do. All one needs to do is to send us a user name and a password (with at least eight characters). It would also be nice if included were an email address and who you are. Send all this to sales@germanguns. com. Except for the now required longer password, this is all stated in the yellow banner at the top of the first page.
Frankly, it could be made simpler but unfortunately, nobody knows how to make the changes
