To facilitate peer support and discussion about aprs.fi I have created an aprs.fi discussion group on Google Groups. A bit like Yahoo groups, you can send and receive group mails using email (just like a regular mailing list), or you can use the web interface, or read the posts using an RSS reader.
If you've got questions on how to use aprs.fi, or if you'd like to share tips or tricks, please join the group and send an email there. I'd also like to encourage experienced users to answer any questions posted by others, if you happen to know the answer. I'd greatly appreciate your support - any time I don't need to spend writing emails I can use for developing new features.
