Hey, good news!
I haven't had time yet to do much more than create the DIY Poetry Web Ring store and smack a few titles up, but I should be able to come up with something pretty slick in the next couple of months (customizing the html template, trying out a few things) and at that point will link it up here. The store will highlight a rotating selection of titles, and hopefully I will also be able to include reviews, etc. There will be a built-in function for submitting titles for consideration, & readers will be able to purchase items from various Lulu.com publishers in a single checkout.
Nifty, eh? Stay tuned.
