well there is www.crochethelp.com. Not sure that it is terribly helpful in crocheting but it is one of my favorite sites to hang out on. :rofling:
hahaha...I've been looking for a good site too--my mom crochet's a little and enjoys it but she isn't very good...I want to find a good visual way (other than books) for her to learn some new stitches so she'll feel better about the work she does. She says everything that she does looks the same.
