It looks to me that project alerts are set by individual users in such a way that if a developer wants to be alerted for any new work items assigned to him/her, he/she will have to set it up on the client he/she is using.

Is there a way for project administrators to set up project alerts? For example, when a work item is assinged to a user, the user will receive an email alert even if the user has not set up project alert himself.

Thanks for your reply but I cannot seem to be able to find bissubscribe.exe or workitem event subscription tool as displayed in the link to the blogs above. Is the bissubscribe.exe supplied by Team Foundation Server? How do I get to the workitem event subscription screen?
