There are numerous avenues of support, from simple announcement lists to full-fledged discussion lists. As well, if you have bugs to report, I have a simple way to do so.
All bugs should be submitted through an automated bug-tracking system. While you might fear that this will cause the bugs to be lost in the aether, it will instead help in the tracking and resolving of bugs. To submit a bug, please fill out the bug reporting form.
If you want to contact me directly regarding questions, comments, or bugs with froi, you can e-mail me. Note that depending on workload it may be a few days before I can reply to your e-mail.
