I’m doing an experiment…using Constant Contact I created a text-only e-mail signup link that matches the font of the items on my vertical navigation bar.  It’s after the last item on the bar, so it doesn’t look like it’s part of it, but I’m curious to see if this style and location will encourage people to click through and join the newsletter mailing list.  So far no one has clicked through the one I have in the middle of the page.
