Great tips jazzy! Great website for homeschooling. I just graduated from homeschool, and wouldn't have had it any other way.
That said, I typically have a "peak" of visitors every time I change my sig on forums. I'm on very few search engine friendly forums (this is one of the few), so I typically don't worry much about the signature. I admit, I really should be more active on forums.
