I'm a super-mod on Maxima.org and there is a regional section where we have quite a few local Maxima guys as members. I'm also an Admin on OhioNissans.com and the site is moving to a new server in the next few days which may get the site a bit more circulation. Also, SgtSchulze on here is also an Admin on OhioNissans.
