Been using MicroStation before it even existed (IGDS on a PDP 1170 and VAX, then PsuedoStation) and still lovin it with V8i/CONNECT! Taught myself MDL and a year later attended the first MDL course ever given by Bentley (and the advanced a year later), after that I've been hacking my way along coding tons of apps. Now porting all my .MC code to 64bit C++ for CONNECT.
