Just wanted to pop on here and share two things.
Neither of which have been updated in a while, but both of which are just as relevant today and to ALL of us as they were when they were setup.
The first one being this: https://www.youtube.com/playlist?list=PLA06Az4-OcVkaXpuQ8TSfVWwi6Q45TjoN
The second one being this: https://last-outpost.net/forum/index.php/board,329.0.html
These guides were written by RPG-X Veterans during the height of TLO. It's a phenomenal resource that covers a great many topics.
As for expanding beyond that, I think the next issue of Ex Astra - Lite will include an RPG-X Master Class type session, to give some helpful tips for those times when you don't know what to do :P
Also Never be afraid to ask questions. I have personally been around for a LONG time. I play RPG-X in my sleep (and nobody notices :P), but the RPG-X staff is knowledgeable. most of us "Old States people" are VERY knowledgeable; so don't hesitate to inquire when you need help (no matter how long you've been around for - or how stupid you think the question is)
I have a saying, that I hold very true. "The only stupid question is the one that goes unasked." (unless you work in retail :P).
Anyway - just looking to help.
