I downloaded the wp-project today from Extend and there was a parse error on the project.php file, and a couple of posts where the author is to busy, it has not been updated for a while (2008).
The code php tags were corrupted <? instead of <?php on three lines 34 47, 53.
I have emailed the author and have uploaded the fixed file, it is fine with the fix, 'WordPress 3.01'
This code replaces the code in wp-project/pages/projects.php
I also want to extend this plugin, as there is not another plugin I can find for simple, timesheet recording.
If anyone wants to colaborate then contact me please!
