First of all, I would like to say that SharePoint Community Rocks!!!
Glen Cooper (my colleague and great SharePoint expert) has started a site called
The SharePoint Knowledge Base. I think, the
SharePoint Knowledge Base will be a great and single place to look for solutions/how-tos/tips& tricks etc., once sharepoint community starts contributing to this site. Please pass on the information about this site to our great SharePoint community for the benefit of the SharePoint community!!!
