Online (free) issue trackers

I've been trying and using various issue trackers in the past months, in particular task2gather and pivotal tracker. This for very small projects (1-3 developers).


I wasn't satisfied with task2gather. In particular, I found it was too much in my way and also often failed in a way that made me lose my data (it clears your form when submitting, and if for whatever it fails, you lose your text). Other limitations (as for *August* 2009):

• lacks attachments (for free version)
  
• lacks text formatting. If I paste code it is garbled...
  
• reassigning a task to a new folder is cumbersome (cut / paste process).
  
• workflow too fixed
  
• I've seen strange issues with duplicate issues with changed titles. No history explaining it.
  
• small inconveniences:
  
  
  
  • like when you create an issue, the url in the browser urlbar isn't
    always updated to reflect the issue url
    
  • for some reason, T2G doesn't let firefox to keep the password.
    
  
  

But I am so far happy with pivotal tracker. There are of course small things that could be improved, but the tool isn't in my way, which is what I expect most from a tool. The fact that is has a simple export to CSV and isn't down is also great. Check it out !
