Can I advertise my professional services in my member folder?

Our terms of use agreement prohibits placement of advertising in member postings.  However, you are encouraged to describe the work you do as well as your training and background.  Also, your author page can provide a link to your own web site if you have one.  Finally, your contribution of content (articles, pictures, discussion postings, etc) can often be even more effective than advertising!  Members can always contact you through your author page.
