Marquee that updates with page info

[KFizzle23]

Ok i'm looking to put together a new site, i've got a rudimentary knowledge of html, very little of javascript and even less of other things (i've built sites and things before, but not coding this one so it should be way easier). I have an idea that I want to do but i really dont know how to go about doing it, or where i can find it (googled but kinda lost).

Does anyone know how to create (and can you help me) a scrolling marquee that will 'update' as OTHER things are updated. By that i mean, if an article on one page is updated could it then update the marquee (by having the Marquee look for a specific portion of text on the article) so that the marquee can let people know 'what' has been updated on the site? (IE If its possible and i set it up with the titles of the individual articles people could see the names in the scrolling marquee, and know if its a new one or the old one)

My intent is basically to have a scrolling marquee that lists 'updates' on certain 'blog/article' type portions, even if i could only list the title of the article, so that someone on the 'main' part of the page would like instantly know if one of a number of things was updated just by looking at the ticker.

I was looking at a DHTML IFrame Scroller which looks like it might suit my needs, I just need to find a way to make the internal html file itself be updated by different sources if possible ... theres an advanced RSS Ticker and a pausing RSS ticker thing here which look good, but I am not sure how to work with RSS stuff, that I might have to check out also this week.

(just an update in case anyone is thinking about this stuff / working on finding a solution)
