you should tell your friend to look for some fine portrait artists homepages if she want to see qualified still-life painting.
Still-life is something in between portrait and landscape, but closest to portrait. In other words, if someone is not good at portraits, don't expect that his/hers still-life's are good either.
Here is a place to learn from:

I can't help you with a forum site, hope that other's can.
