I have updated the Storylog (v0.29) and Storyfilter (v0.39) plugins for Blosxom. Both now include file locking so there should be no problems with simultaneous access to a site causing file corruption any more.

Storylog now includes an ignore list for URLs and user agents so search engine hits can be ignored so they won't affect the 'most popular clicks' list.

Storyfilter now has the option to generate a list of all keywords, which is useful for site maps. This requires the line
meta-showkeywords: yes
to be included at the start of the story and fills the $storyfilter::allkeywords variable with the list.

Both plugins can be downloaded here.

Storylog is another Blosxom plugin. It logs the category views (and if storyfilter is installed, optionally logs keyword links).
Download the current version (version 0.20).
Instructions are in the zip file (no perldoc yet). For a demonstration of storylog in action, see the 'Most popular clicks' in the menu bar on the left. This uses the 'combined' log of both categories and keywords.
