Research & Rescue now has a microblog, called The Holding Pen, up and running. None of the methods available for archiving tweets were really all they were cracked up to be, so this is a way that R&R can microblog all the tweeted links that go out. For the most part, there will be no commentary included but this also leaves room for attributing the original tweeter, if was a retweet or the Facebook poster if he or she has a blog that can be referred to.
Apologies, in advance, for not having the previous posts categorized. I'll do that as I have time.
You can get to the Holding Pen by going the navigation bar at the top of the page and clicking on the Microblog link or by bookmarking the URL for it: https://researchandrescue.typepad.com/holding_pen/
