I added a feature to the Oddmuse:Indexed Search code. Now you can exclude pages with a certain tag from searches. And the first use I made of it was to exclude the RPG tag from my Diary page. Unfortunately the journal RSS feed is produced by the Oddmuse:Journal RSS Extension instead of the main code. Thus, it has no support for searching, and thus the exclusion has no effect. Damn.
I think the correct solution would be to add a match parameter to the code that produces the default RSS feed. Except that the Journal RSS Extension also changes the sort order (alphabetically instead of by last modification date).
Time passes...
I added a search parameter to Journal RSS Extension. 😄
Thus, new RSS feeds!
