Because spam boots have cracked the captcha systems, even the one used by gmail, in the last two days we had hundreds of spam boots registrations and I have been forced to disable registration to stop it.
As many other sites, we will have to switch to manual registration. To join, the new user will have to drop an email to us and we will assign to it a temporary password.
If you have questions on this topic or problems to register, mail us please and include full name and contact data.
