If developers [*] want to use JetBrains IntelliJ IDEA for their work with Apache Forrest, then you can get an Open Source License: http://www.jetbrains.com/idea/opensource/
You can confirm your personal participation in Forrest by providing a link to mail archives. Certain archives provide an "author" search, e.g. http://marc.theaimsgroup.com/ [*] never sure with these licensing schemes whether by "developer" they mean a developer or they mean a committer. Anyway, just ask. -David
