On the advice of a JREF forum member (Alice Shortcake), a local group has started http://www.stoprobbie.com/.
The direction of the site is, obviously, not determined but the goal will be to let people know who Robbie Thomas is (as I say, to give Robbie more publicity than he could ever dream for). I will happily contribute to Stop Robbie Thomas but my blog will continue as it has (likely with a little less focus on that scumbag).
If you want to help with the Stop Robbie Thomas site, you're encouraged to email them at firstname.lastname@example.org
Help promote the site by linking to it from your blog or website.
