Martin,
After I posted my latest announcement, I was returned to the top level of this forum and noticed that the discussion Test version of TeX filter for moodle.org showed that the latest post in that discussion was on Feb. 16, 2pm. However, when I look at that discussion, the latest post I find there is your post http://moodle.org/mod/forum/discuss.php?d=5228#24392 dated Feb 14, 6:52am.
