You can enter your (ISC)2 member number into the channel survey that appears before you register for or watch your first webinar that is hosted by (ISC)2.
When filling out the registration form for an (ISC)2 webinar, you will be prompted to fill in the following form (right side) that includes your (ISC)2 member number.
Important: Once you have entered your member ID, (ISC)2 transfers your registration information into their internal database, and BrightTALK will no longer be able to modify or add the number at a later point.
If you need to add, modify or verify your member number after you have watched a webinar on BrightTALK, please contact (ISC)2. You can contact (ISC)2 by calling +1.866.331.ISC2(4722) or emailing membersupport@isc2.org.
