Hillside keeps a list of members, which includes each member's name, address, and email address.

Candidates must be nominated for membership by a Hillside member.

Candidates are admitted to membership by the board—this may be delegated to a designated membership secretary.

Members may resign, or choose to become emeritus; resigned or emeritus members can rejoin at any time.

Benefits of membership:

• you are on the members' mailing list

•  you are invited to the Hillside Annual Meeting (post-OOPSLA every year)

• you can influence the direction of Hillside and the patterns community

It is expected that new board members will have been Hillside members for at least 1 year before they join the board.
