I joined yesterday and created an account. I could not find the project that I was going to be working on via any searchers, including the leader of the account by name or email. I figured it might not be public or such, so I had them send me an invite.
When I clicked on the invite or the project board they initially sent me, it did not join but took me to the search page. I could not get past this from any link; even the email Asana sent me to join their project. I eventually created a dummy project, and it took me to the real one I was invited to.
This seems a bug, but worse there is no help support or any way around it. Were I not a curious developer myself, I bet most folks would be stuck. I had to search google even to find the support page to get help. I understand not wanting to field a thousand random questions, but you have a big FAQ, why not link to that on every page?
