Ask the list

Many of the original authors and anyone maintaining or extending the code reads the list. The traffic tends to be bursty. It usually focuses on build problems and troubleshooting. Again, the more specific your question, the sooner you'll get a useful reply (if it comes).

Tip: It's your subject line, Use it! Try to convey source of the problem (not how you feel about it) in four words

It's important to convey your setup and configuration.

SQL Server version
FreeTDS version (or snapshot date, if not a release)
which client library you are using
what language or Perl module, as appropriate, you're using
your client OS and hardware architecture

Please, do not email the authors directly. You may well be ignored because they're they type that gets a ton of mail. Anyone willing to address your question reads the list, and you don't want to offend anyone willing to help you by going about it the wrong way.
