The AeroGear team tracks issues for all of the AeroGear projects in the AeroGear Project in the JBoss Developer JIRA. We do prefer if you sign up and create issues there. See the AeroGear JIRA Usage and Guidelines Guide for information on how the issue tracker relates to contributions to this project.
We understand that for some people, JIRA can be a barrier to entry for creating issues and contributing in general. The maintainers of the Voyager Server welcome issues created in GitHub. Feel free to Create an Issue and select from one of our issue templates. We will do our best to triage these issues in GitHub.
If you have a question about Voyager Server that is not a bug report or feature request, feel free to create an issue using the help issue template.
You can also reach the aerogear team at #aerogear on Freenode IRC or the aerogear google group.
