Could be an error with Mino's account being in wrong user group. He doesn't have an user rank as well as he can't upload avatar so I guess his account is currently on the unverified user group so one of admins has to switch it and move his account to the standard/regular user group like the other members.
There are many usergroups like admins, mods, members, banned members, unverified ones (usually when a member doesn't confirm his account when registering then his account is still limited in access like example Mino's one), ect ect. I can be wrong, but as far as I remember it has to be something like this, so one of admins can fix it quickly.
