I’ve moved a couple of little plugins and templates onto our Subversion repository; you can find them in the extras directory. Hopefully this will make me more inclined to keep them updated—as they stand, they’ve been tested on the latest version of Tarski, but of course if you have any problems with them just post on the forum.
I wrote some .htaccess redirects, so all the old links should be redirecting (if you find any broken ones, please let me know). Tarski 2.0.5 should be out early next week, with the usual bug fixes and enhancements.
