Installed without any problems. Works out of the box.
Had a small issue with another component that caused a collision on the function isFrontPage, but this plugin is so well written and so well documented that it took me less than 1 minute to fix all the collisions.
Thanks, great, great plugin.

These guys know what they are doing. The module works out of the box (on Joomla! 1.0.15) and it has exactly the configuration options needed to balance great performance with great usability.
Limiting the number of rows to search is a great idea, simple and effective.

It's a great effort and it will work well on small sites. However, as your content starts to grow there is no way to limit how many days to look back to create the tags. The result is that the SQL query is too big and you receive errors.
If the developer added a way to limit the query to x number of published items, or items published within a certain date range this would be a perfect module.
