If you're thinking about joining this forum just so you can post some spam, advertise your product, or for any other reason except you want to hang out with fellow STOC members --
Forget it.
This is a forum for STOC members only. If you're not a member, and you don't feel like becoming one, don't bother signing up.
If you sign up and then post spam, within a few minutes your spam will be deleted and so will your account. So you'll have wasted all that time typing your spam, registering, and posting it for nothing.
So, don't waste our time and yours, ok?
Have a nice life...
