Hi Amy
Thanx for your reply first of all, and i also now see your IMOH (sry for that 1)
For me as a user - i am of course really conserned about how joomla works in terms of SEO and this is also why i dont use the 1.3 version and patiently try to wait for the j1.5 to be stable before i get my site online again.
IF then using sections as links is not such a good idea = i think it should be expressed clearly in the sample content because of the fact that it is important to try to learn people about SEO right from the start (newbies like me). And telling them that if they use sections as menu links = they will not be to ok on the SEO part.
Only my oppinnion 
I thought of structuring my site like this:
Sections
------------------
News
Articles
Reviews
Tools'N'Tips
Entertainment
------------------------
Categories
----------------------
Poker News
Casino News
Poker Articles
Casino Artilces
Poker Reviews
Casino Reviews
Poker Tips
Casino Tips
+more categories
------------------------------
The above example is impossible then if i cant link to those sections in order to keep my fokus on SEO...
If i where to set up a structure like this:
Sections
-----------------
Poker
Casino
-----------------
Categories
--------------------
Poker News
Casino News
--------------------
it would really limit how much i can "be free" in terms of content items(news, articles etc) and i could not at all link to a part of my site wich contains the news from many categories..in 1 link..this of course because i cant link to more than 1 category for a link item (category blog layout)
But i am so lost in this now that i probably missunderstand it all, so sorry for that part - i will probably figure out this sooner or later

Only important thing for me is that if linking to a section is bad for SEO in joomla - it all gets really confusing...
Anyway - i shall not bother you with my "none-understanding" mind because i see that most people get this easy (that even scares me more lol). Anyone got a couple of IQ's left over to share btw? (hihi)
Amy - thanx anyway - aight
UPDATE: I found your PM Amy - i have answered it now...
