I don't know if this is the right place to ask this, but then again I don't think there IS a right place to post this. I am only wondering why the forums member by the name of User is just an ordinary member now. IIRC, he used to be an AK or a mod. Did he resign or something?
If you're curious, I'd suggest you PM him and ask him yourself. The reasons for stepping down are often personal ones and I'd rather they weren't discussed in a thread without his knowledge or consent. Not to mention he'd be the only person able to give you a truly accurate answer anyway. ;)
