In the current beta 2.6c release are the following improvements over the original P2 and GTD by Templatic:
- You can type in “@username” to send email notification of new messages.
- You can click on the user name checkboxes to also send notifications.
- You have your choice of 3 color schemes
- We made it easy to get started quickly on new WP installations;
activating this theme will also automatically activate the calendar, tag cloud, blogroll links, and recent comments on the sidebar.
- We’ve also fixed numerous little bugs like getting 0 byte attachments in the notifications that were in the GTD theme.
