This looks pretty great. Signed up and taking a tour of the internals. However, I don't think I'll be using this unless the following are addressed: 1) doesn't appear to support external users. I can't seem to give a client access so they can comment on tasks, answer my questions or track my progress. All people you invite to a team appear to have unfettered access to all things. 2) no spec/pricing sheet on what's included. blog says "is and will remain free for teams with up to 30 members", but how much will it cost afterwards? Also, for the free plan, how many attachments can I add? What's the max size of an attachment? I don't want to invest my time into a new thing and then hit some invisible limit. (Yes, I've tried to look in the support/help faqs) 3) import/export. will you make it easier for me to move in from my current system? once I'm in the system am I locked in? I'm currently using Apollohq, and it's been doing pretty well. It has all the features I mentioned above, as well as time tracking. Only thing is it costs money (a bit too much for my small team) and they've been slow to get a phone-friendly version. The interface has also slowed down since the beta, but for the time being I'm overlooking it because I expect growing pains.
