Hi, I have problem with my task. I must make a program in .NET (C#) to communicate with SharePoint and Live Communications Server. .. .. When I set-up alert on my SharePoint web page document, I will be notified with e-mail, but I will be notified about any change of my document sending InstantMessage to my Messenger instead of sending mail to my mailbox. I have't any idea how to do it and where shoud I start. How SharePoint processes alerts, are there any events to catch or is there any class to use? How will Live Communications Server handle with this alert? Thanks for any ideas or examples.
