Community
The OAuth community is dedicated improving the spec and library codebase, spreading awareness of the protocol and documenting and showing, through screencasts, wireframes, mockups and other illustrative designs, how best to put OAuth into use.
Please visit the community wiki for information on test cases, contributing and more.
Mailing Lists
The OAuth Core Mailing List is where you can ask questions, get help, and get to know the rest of the OAuth community.
Membership on the list is currently open and you can subscribe. The archives are also open and are available for review.
Additional OAuth Mailing Lists can be found on the wiki (for example, language-specific lists).
There is also an OAuth mailing list setup for work related to IETF standardization.
