 - NeuroStars: The NeuroStars forum is to be used by tedana users to ask questions about how to use tedana. tedana's developers may answer usage questions on NeuroStars, but development-related discussions should happen in GitHub Issues and PRs.
 - Mattermost: There is a `tedana channel in the BrainHack Mattermost`_. This is primarily used for online discussions during BrainHack-related hackathons (for example, the annual OHBM hackathon), if and when there is a tedana-related project. We also use this channel to redirect to **existing** Issues and PRs, whether open or closed.
