No offense, but if you send me an email with a bug report, there's a good chance that I won't get to it right away and if I don't get to it right away, there's a good chance I won't get to it ever.
On the other hand, if you post that bug report to the appropriate CPAN RT queue (and my modules generally even list a nice email address for you to do so without using the Web site, if you don't want to), then I will get to the bug report. Eventually. I forget email. I lose email. I don't lose RT.
I know many other CPAN authors with this same complaint. Please don't send us email about bugs. Use RT.
