Re: #rss-reader# and top nav modification via snippet on LEC2
that snippet is actually what powers the reader for your REW blog in the right hand side, it's not something you can use for external feeds or that should be modified (at least I think that is what it does)
As for adding sub links to the main links (you can't change the main ones we need to do that)
All you have to do is select that page and then either click "add sub nav link" and fill in URL and anchor text, or "add sub page"
Starting LEC 7 soon but it won't be called LEC 7 - LEC 2012 coming soon!
