A number of users have encountered difficulty registering for this site in recent months. In response I disabled the registration screening program for new users a few days ago. Bad idea. It resulted in number of dubious new user accounts, which then invites all sorts of mischief. I re-enabled the registration screen, without the Captcha feature that caused some of the problems and with a requirement that I approve all new registrations. I’ll approve everything that looks legit but if your email address is $ellVia#grAfirstname.lastname@example.org, you’ll need a note from your mother to gain entrace. I apologize for any inconvenience, promise to act expeditiously on all new user requests (at least until I can fiddle with the code problems that caused the glitches, which may take some time given my lack of coding expertise, and if you are a real person and I deleted your account, mea maxim culpa.
