I don't think I've missed anyone, but if I have or made any errors, feel free to let me know, and I'll correct it as soon as possible.
Just because Binkmeister's a LEGO Ambassador, it doesn't mean he needs a spot: he runs this site, after all. 
Thanks go to Kahu Rider 13, Clark Kent, Sidorak, Turaga Dlakii, Sumiki for the helpful info.
