I've compiled a brief overview of some of the tools/resources. I'm not entirely sure what you might be looking for, but I've listed some of the key features on each platform so you can figure out what your needs are.
##Breeze This one is probably my favortie out of the bunch, but the limitation is probably cost. Depending on the amount of users, cost will increase as you add users. Although I tried it for free and the interface is simple, there's a nice calendar view, and you can breakdown projects however you want (teams, tasks, goals..etc).
##Zube This one integrates well with github. This platform is like waffle on speed. Its free and open source and there are additional features like "burndown" where you can check analytics. Only con is that this tool seems like it's more project based and team based.
##Open Project This one costs money as well, but I thought the most useful tool on this platform was it's project timeline feature. Not crazy about this one but it works.
##Jira This could be overkill for us, but it's a common project management tool in a lot of software/develop centeric palces. I though I'd throw this in as something we could consider if we scale. Jira is a little more complex, but can also track many more aspects of teams or projects.
Hope this helps :-/
