Sticking with my theme of team collaboration, I often rely on Premier Field Engineers (PFE's are responsible for providing onsite support for Microsoft customers) for a number of things and they’ve always delivered. They are in short supply and are highly coveted, especially those that are specialists.
One such PFE is Robin Meure who specializes in SharePoint. He has a wealth of knowledge on this product and lest he admit it, a guru when it comes to quickly and efficiently solving complex problems. He of course has his own blog so be sure to check it out and see if the problem you're trying to fix has already been solved. If not, add a comment here and we'll see if we can persuade Robin into writing a post on it.
Oh and if you’re going to the Netherlands, don’t ask him about Amsterdam. Cheers!
