We now use the Gaia GPS subreddit for forums. You can join the forum here: /r/gaiagps
You can use this forum to ask questions, talk with other users, or post links of interest to the Gaia GPS community. We also do our beta test discussion on this forum.
For feature requests or suggestions, visit the Community Forum. Add and vote on ideas, and get notified when ideas get worked on. It's a great way for us to gauge community interest and we often consult the forums when looking to implement the next big feature in Gaia GPS.
