There isn't a "ghost admin" on the org...however, there's only one person who reviews the new accounts. The site has been hacked in the past, and now the admin is being very careful with new members. It's a great site, and the depth of info there on SH is "the" best and most up-to-date, IMHO.
If you have any more trouble, LMK, and I'll ping the guy who reviews the accounts...I'm a gobal mod there, but not an admin.
