Nice job, Cate ... very informative ..
Are you including a resource box at the bottom of all your articles?
Pretty much all article submission directories have a seperate field for that ... or a sig. file, and along with tying in your links within the flow of the article, it's the 'legal' spot for promoting your contact info, website, etc.
Forgive me if you're fully aware of the aforementioned ..
Much success,
Mike 'would like to write a new article every day' Merz
