The 21 June UK User Group Community Day at Microsoft UK offices in Reading is rapdily filling up. If you want to attend I would advise booking soon. The day will include presentations from the PowerShell, Exchange, Groove and Sharepoint User groups among others. There will also be subject matter experts attending who will be able to answer any questions you may have about the technologies.
