I'm moving us onto SQL Standard from SQL Express which is what the corporate intranet site is running. That upgrade was tested, and I'm doing production today. I've also setup some proper backup jobs for the database.
Starting tomorrow, I (and another engineer here) are redoing the Sharepoint structure, permissions, etc. It should be a lot more clear, and easier to understand what people are up to.
I haven't done a lot of Sharepoint administration, so it should be a good learning experience!
