Glad to hear that you installed MVS on 2.3.3 too. Naturally it is lot of code integration because of the mighty add-on (thank you all). I plan to go the same route to heaven. Did you had to modify code or 'just add tons of code' according to the instructions? You mentioned that you are not a php expert... I'am not, too. The thread here is well kept and full of helpful information, that makes me optimistic.
