Get your Conversations and Project colleagues from Projectplace. This is not an official Projectplace App, but it still rocks!
This is the Chrome version of the Safari Extension for Projectplace
A total remake of the extension since now it will not help you to simply sign in and present the number of unread Conversation in Projectplace, but give you a complete window that will let you browse conversations and comment on the same.
No more saving of email and password in the extension since I now use oAuth provided by Projectplace.
