This site is worth a good look.
It has been setup by Justin Taylor who used to work for a large UK reseller and before that Autodesk UK. Justin moved from the UK to South Africa last year and is now working as a technical consultant for a reseller called Modena, http://www.modena.co.za/, which is based in Santon near Johannesburg. He has setup this site to push the merits of Revit for the South African market place. Drop by his site as it has some interesting thoughts and articles on Revit which are worth a look.
