GmailSync on codeplex
By far the most popular tool that I published is GmailSync which was also features on Lifehacker. But as I get busier in other projects, it is getting difficult to put more effort into it. Its been a while since I put the last update so I've decided to upload the sources hoping that I can find someone to lead on this.
You can download the binaries and check out the sources from the following url. As the source code is not the best I've written so I'm willing to work with anyone who is interested.
