LOL!
Took me awhile to figure it all out myself....for one thing, I have a subscription, there are some things that non subscribed members can't use or view, and I think stamps is one of em, and I think journal css is another...that shit took me forever to figure out.
Just click around on the modules, see what you can figure out, it's how I learned...and I still don't know half of what I'm doin'!
