When a ChipGuide member logs on, a check is made by the logon program to see that they are a current member of the CCA. At issue is that members don't want to have to log on once a week. Previously, ChipGuide logons never expired, once logged on, you stayed logged on until you logged off. But we now have a different situation because of the recent change to the ChipGuide where only CCA members can access advanced features. Therefore a regular check of CCA membership status is needed. It is done once a week when members logon.
