Haven't done a course as such, but there are some excellent websites and podcasts out there for beginner enthusiasts.
Two great podcasts that I love are:
The Digital Photography Show (audio only)
Photoshop User TV - okay, that's more about post processing with photoshop but still very good.
Blogs that are useful are:
Digital Photography School also has very good forums and weekly assignments etc.
Photojojo is great for some really creative and bizarre tips/projects/ideas.
Scott Kelby's site Bit more advanced but he's a bit of a photography guru and is well worth reading.
That reminds me - Scott Kelby has written some fab books - well worth hunting them out at the library. The best one for beginner SLR owners being The Digital Photography Book - not a very snappy title I know, but probably the most recommended photography book I've come across.
Also check out camera manufacturer's sites - they quite often have various tutorials up on site that are worth looking at.
I'll have a think for some more, but they're good starting points!
