I registered my Chousho account on my board (user id 2) and did not complete the e-mail confirmation. Instead I logged on in another browser to my admin account (user id 1), set Chousho's User Group to Administrative and the account to valid.
I could not see the Admin option for Chousho. So I added secondary groups Admin and Mod. Still could not see.
I had to go through Administrators, add admin, select my name and then it would show up. Through this action, the only visible difference to me is the un-checking of "Administrative" in the secondary user group on admin.php?users/chousho.2/edit
Is this a bug, or merely a bit of a mix up? It seems like it could be a bit more intuitive.
