Hi,
i just registered for the forum to report a prob with my Monomachine. I stumbled upon the following problems with your site on that way ,-)
Obviously, there's a subdomain dev.elektron-users.com where I registered (followed the register here-links from the main page) which you're still able to register. I did that but cannot post in the forum at all. Probably because the credentials are not transported to the main site's forum?
Hence I had to register twice but couldn't use the old email address anymore. This means there's some exchange between the two sites.
Anyhow, hope I helped you improving your site with this rant
