Indeed, there are reported bugs which need fixing.  Our comrade fallen  
seems to have a good grasp of the key issues. One pointer to them is but there are of  
course other bugs. And there may be some yet unreported.

Also of key importance ... we need more people/users/us getting more  
involved in Calendar bug reports and topic reports at Getsatisfaction.  
  Only 50% of calendar/lightning topics got a reply last year (50% of  
those are topic type=problem) - which I think compares favorably  
against the average getsatisfaction response rate, but it would be  
nice to do better. Example unanswered topics:

you can find topics using tags like and and/or  
follow via RSS

Likewise, more people are needed to help in bug reports. Like

Lastly, fallen said in my last conversation with him that we still  
need a kb support article to guide users through basic troubleshooting  
for Calendar, such as performance issues.  It would be VERY cool for  
someone to do that so users can self-help / self-medicate :)
