Using LinkedIn quite extensively, I created a group for CISA qualified professionals to join.

Please visit the following link stating your ISACA membership number and month & year you qualified for the CISA.

Upon joining you’ll have the following logo of the CISA letters I made displayed in your profile.

July 2008 - A quick update on the CISA group. We now have over 1300 members in the group! 

The group is still only intended for CISAs, as each application is viewed, please also ensure you have your relevant CISA certification & experience detailed in your profile.
