We have settings requiring potential new members to use Q&A captcha, respond to a custom profile requirement, and Admin is supposed to approve all new members. However I happened to notice on the front of our Board a "welcome" to our newest member (name) which is not one I recognized. There are only two people with admin privileges, and I checked the ACP logs to see who approved the new user - no one, nor was the user waiting in the INACTIVE USER list for activation. This user was also listed in our NEWLY REGISTERED USER group too. Haven't seen this happen before, so suggestions on solving this mystery appreciated.
