Thunderbird 3 Release Candidate 2
As an early adopter I am using Thunderbird 3 for quite a while now. The Betas have been really stable and other than a few minor glitches I had no problems.
I just saw that RC 2 is out there after RC 1 was released in the last week. Be careful with the release. My copy was crashing every time I tried to send an email. I couldn’t figure out the exact problem yet but not being able to send messages is quite inconvenient in my opinion.
