We are happy to announce that GroupCamp is now integrated with Google Contacts for accounts installed from the Google Apps Marketplace.
If you have a GroupCamp account attached to your Google Apps domain, you can now browse all your contacts to add users to your GroupCamp account. Please note that an administrator of your Google Apps domain must first grant access by GroupCamp to Google Contacts data. This is done in the Google Apps administrator control panel.
The rest is straightforward. For instance in the new Guests application in the administrator section use the ‘New guests from your Google Apps contacts’ link to add users from your list of Google contacts.
