Firstly, considering that REBOL actually runs under AmigaOS/68k, this is as good a place as any to discuss REBOL issues. You are by no means out of line. I have long been a supporter of REBOL on Amiga.org. Secondly, the creator of REBOL is also the person who conceptualized and wrote the AmigaOS in the first place, so that makes it more Amiga related than even DE. It is a very simple statement to make, since the same creative mind is behind REBOL as was with the Amiga. That's the bottom line, because Targhan said so!
There are several user groups, online communities, and portals for REBOL related things. Just pop up a google search for REBOL Forces (that's a french group that produces an ezine for rebol users), look at
www.rebol.org, which even has contributions by your's truly, and click on the language link of rebol.com. There is a wealth of information on
www.rebol.com, but you have to dig for it.
There is also several mailing lists, one of the oldies is rebol-beginners. It may be a yahoo-groups mailing list now. Just search on google for rebol + beginner.
Finally, I may be able to help on some of the simple tasks and concepts. I've written several rebol applications, including a webpage generator.
I wish you good luck on your REBOLling!
