You know Angelina Jolie had a flying submarine in Sky Captain.
Keep him a sub just let his post count keep climbing. It is the post count you look at to see if someone is a regular poster (to my way of thought) not the “rank.”
Expect about 1/3 of the posts in the Variants forum to be moved there. If a post of yours has disapeared, theres a good chance I put it in there (might of done it by accident, kinda Mass-Modding here :))
