project pier

Project Pier is "a Free, Open-Source, self-hosted PHP application for managing tasks, projects and teams through an intuitive web interface". In a nutshell, it's a Basecamp alternative.

Task list comments

As of 0.8.0.3, current stable version of Project Pier, there are no comments for items on task list. Coming from Basecamp, I really missed that feature, so I found a patch for 0.8.5.x-dev, which applies with errors to 0.8.0.3. Here's a modified version of the same patch which should work with 0.8.0.3. To apply the patch, copy it to the root of you Project Pier install and do:

$ patch -p0 < project_pier_task_comments.patch

Don't forget to backup Project Pier's directory before applying the patch.
