I have recently booked to go on a couple of interesting conferences for work:

The Web: A Powerful Recruitment and Communication Tool
Date: Tuesday 20th May 2008,
Organisers: CASE Conference

New Challenges, New Opportunities The Role of New Media in Crisis Communications
Date: Friday 6th June 2008,
Organisers: CIPR Education and Skills Sector Group

The second looks particularly interesting as a guy from Virginia Tech University will be attending to talk about how they dealt with communications around the shooting on the campus in April 2007.
