[Radiant] 0.5.2 -- Setup and design

[Andrew Klein]

Hello all!

Still getting a hang of this all and just looking for some 
input;insight. I've been running a fairly simple design of Radiant 
(Read: almost source) and want to expand the design a little. Here is 
kind of what I want to do:

- Home (Shows either just News or all of the <dont know> heading, 
chronilogically)
-- <dont know what to call>
--- News
--- Articles
--- Tutorials
-- Downloads
-- Gallery
-- RSS (Covers chronologically the news/articles/tutorial tree)
--- RSS <one for each of the news/articles/tutorials>

I just need some insight on how to do the RSS feeds. Also, curious if 
you could include 'categories' somehow or 'tags' for each Sub under all 
the categories.

As well, wondering if there is plans for a commenting system. 
Originally, when I was looking at using Radiant, I seemed to remember 
there being a third-party site for including managable comment system 
and as such I was going to use that, but so far the only one available 
is pretty crappy that I can find (Don't have link; I left pretty 
digusted at it)

Sorry for the ignorance right now. I am just trying to get up and going 
again and having a duck of a time.
Thanks for all the patience!
Andrew
