Community Day is back with the Fourth Edition of this annual community event on Microsoft technologies!

Fourteen Microsoft User Groups combine their efforts to organize this unique networking and knowledge sharing
event. With so many new releases from Microsoft, the theme of Community Day 2010 is of course 2010: a new wave of products and technologies. This means that most sessions will be looking at Visual Studio 2010, Silverlight 4, Office 2010, SharePoint 2010, SQL Server 2008 R2, OCSR2...

Microsoft Community Day will take place on Thursday 24th June 2010 in Utopolis, Mechelen, where we will
bring together over 300 IT Pro’s and developers.

I was chocked that I didn't knew the answer to this question immediately, offcourse we all know the result of putting someone in CC or BCC... :)

so here we go:

Cc
Cc is shorthand for Carbon copy . If you add a recipient's name to this box in an Outlook e-mail message, a copy of the message is sent to that recipient, and the recipient's name is visible to other recipients of the message.

Bcc
Bcc is shorthand for Blind carbon copy . If you add a recipient's name to this box in a mail message, a copy of the message is sent to that recipient, and the recipient's name is not visible to other recipients of the message. If the Bcc box isn't visible when you create a new message, you can add it.
