Need newbie help

Hello,

I've been fiddling around with Xaraya for a few days now, though I still
don't have a clear picture of what I am doing.

What I want to learn is how to build themes, manipulate templates with
different types of system variables, write scripts (e.g. different things
based on different permissions etc.)

Quite honestly, I am a li'l confused about all of this. If there is anyone
who is willing to guide me through the basics, and is willing to sacrifice
some time, I'd really appreciate it.

To reciprocate any help that is offered, I promise to write some good
tutorials once I understand all this myself to help future beginners and
newbies to Xaraya.

Asad
