A common 'complaint' I get from people using our site is that they cannot determine which groups have been updated since the last time they have logged in. As a result, they need to click on every one of their groups, one at a time, in order to see if there is any new content. This can be quite tedious if you're in many groups, and leads to decreased usage over time.

I would therefore like to add the date a group was last modified to the results displayed by the Groups Viewer webpart. Specifically, this is the last date that a new contribution was added to the group (to the group forum, messages, docs, etc.). This is not the date that the group administrator last updated the properties of the group.

Is it as simple as adding some code to the GroupsList transformation (Community - Transformations Document)? If so, please advise on how to do this.

Note: While I know this is probably very easy to accomplish, please keep in mind that I am a webmaster - not a developer. Thanks for helping a newb!
