Yes. There are two useful mailing lists. First, we run an extremely low traffic mailing list solely to announce new versions of HTCondor. Follow the instructions for HTCondor World at http://www.cs.wisc.edu/condor/mail-lists/. Second, our users can be extremely knowledgeable, and they help each other solve problems using the HTCondor Users mailing list. Again, follow the instructions for HTCondor Users at http://www.cs.wisc.edu/condor/mail-lists/.
If you have any questions that are not listed in this FAQ, try looking through the rest of the manual. Try joining the HTCondor Users mailing list, where our users support each other in finding answers to problems. Follow the instructions at http://www.cs.wisc.edu/condor/mail-lists/. If you still can't find an answer, feel free to contact us at condor-admin@cs.wisc.edu.
Note that HTCondor's free e-mail support is provided on a best-effort basis, and at times we may not be able to provide a timely response. If guaranteed support is important to you, please inquire about our paid support services.
