I have a .NET ecommerce app that I've integrated with SF.com via the SOAP API.  Everything works great except for one thing.

You know how if you're Chattering you can type @Name and that person will receive an email notification?  I can't figure out how to do that via the SOAP API.  I tried including @Name and @[Name] in the FeedItem Body but that didn't work.  I even built an HTML anchor with the user's ID (I saw this in the HTML source of a Chatter page) but all that did was display the anchor as text in the Chatter item.

Can anyone give me any guidance on how to accomplish this?

Thanks,

Bill...
