Just interested to see how long you have been using SharePoint and which version did you start on ?
I have been working with SharePoint full time for the last 7 yrs.Â
Since SharePoint 2001 was in beta, what fun that was.  Someone posted about the M drive, I forgot about that, good memory 🙂  The main thing I remembered was editing the VBScript in a tiny little window at the bottom right of the page.  The rest is buried deep … well … hidden … for sanity’s sake!
Since about 2008, when I started looking at MOSS, coming at it from a MS infrastrucure background, spent about 3 years involved with the design, implementation and support of a 25k user farm, then left than organisation, took 6 months off, then joined another organisation and seem to be doing the same thing for them, but with 2010 – will have been here 2 years at the end of August.
I’ve been using SharePoint since 2007, roughly 5 years or so.
We’ve recently moved on to SharePoint 2010, and hopefully shortly 2013.
