Due to a flood of fake user accounts being created, I am temporarily closing all new user registration on the site. My understanding is that this is a known issue currently in the DNN ecosystem, and it is not a specific targeting of this site. 

The solution is to replace the existing CAPTCHA verification system with a different system, which I won't  have time to do until this weekend at the soonest. 

In the meantime I have to take this step, because I am (rightfully) getting bombarded with emails from random annoyed and/or concerned people who  have never been to the site but are getting registration emails because a user account was attempted to be created by this fake user botnet. 

One assumes that the goal is to either just cause disruption for the entertainment value, or to attempt to get a working login so they can harvest the user database. In any case, I need to shut off new user registration completely in order to stop the bleeding, and then I will fix the underlying problem when I have the time.  Thank you for your patience. This should not affect existing legitimate users in any way.
