I noticed that the Collective 3.0 has "Add URL(s) to Schedule". I assume you've built this feature in because there are SE's that you resubmit to on a regular basis? What search engine are you comfortable resubmitting already indexed pages to? I hear it's safe to do that with Ink, I also hear it's a great way to keep pages from being dropped out of INK.
The feature seems like a great one - sure would love to know which search engines you had in mind when you developed it???
BTW - did the e-mail notice when some replys to a post go away or am I just overlooking it?
