Membership Types

COMMON allows you to become a COMMON member through three different membership options: Individual, Corporate or Local User Group (LUG):

Individual Membership gives you the exclusive benefits of being a COMMON member. It provides all the membership benefits that COMMON has to offer to the individual only and is non-transferable.

Corporate Membership allows a company to pay a single annual fee, and then all employees of that company can enjoy all COMMON membership benefits. One person from the company is designated as the official representative, and will receive all COMMON communications.

LUG Membership is available only to Local User Groups, Affiliated User Groups and Sister User Groups. One person is designated as the official representative and will receive all COMMON communications. Similar to Corporate Memberships, LUG members can take advantage of COMMON's membership benefits.

All COMMON memberships are annual, and are valid January through December. Memberships cannot be prorated. Membership is required in order to attend COMMON's Annual Conferences and participate in members-only webcasts.
