I'm starting to use Advisors and Participants.  It looks like there are both client-side and server-side participants.  However, reading somewhere, I saw a statement/recommendation that client-side participants (and advisors) may not cause modifications to the repository.

I'm not sure I quite understand client-side participants for a WorkItemSave action, for example.  So this java code would be run on the client (so Eclipse client or Web client) after the work item is saved?  If so, then if I can't make modifications, does anyone have an example of what this might do?  Most of the things I am thinking of for follow-up participants would be modifying the work item (add approvals if not already added is one of them).

Thanks
Susan
