I'm hoping getting some money out of PT would make them act faster on the things most in demand in their user feedback site. http://community.pivotaltracker.com/pivotal [It appears as though] they've not been doing anything at all on these fronts for many, many months:
* markdown (code blocks, anyone?)
* editing or deletion of comments
* grouping stories
* replying to comments by email
[Edit: list formatting]
