I would think that if you had access to his account, you would at least see the admin panel on the top right of the forum index. But I don't know, I did notice your account number is just a few off from his, and at one point I know you had a ZFGSDK status which would have given you increased permissions; unless you still have them in secondary.
One time I remember myself coming across an error in the tabs. I would be posting a new topic, and then I would right click either something in the Projects or Resources tabs and that would lead to a page saying that I was not allowed to post new topics there. I don't know, I can't remember the specifics beyond that for how I engaged it - it could all and well be fixed now.
