I had to laugh - talk about timing. I got an email this morning from Linkshare UK that announced the new location of their head office. Then literally three hours later I got another email that their office was closed due to a local security alert. I can see why they are moving! (Kidding!:P)
Just passing on the info here if anyone needs to contact them in the UK for whatever reason effective Monday April 30th:
16 High Holborn
London, WC1V 6BX
Phone: +44 (0)20 7427 8120.
Note: this is not an endorsement to work with them, it's just an FYI in case you need to contact them and can't.
