Andrew has passed away on April 22nd after a long illness.
His obituary can be found here:

It has always been my impression that LDM was a work of art that Andrew devoted a substantial amount of time/years to. He was quite dedicated to the creation and development of LDM.
This version and the 3.8 version of LDM are marked as reusable code. This means that any coder can take up this project and prevent LDM going to waste. It would be a shame that after all the years of work and dedication Andrew has put into it, it could no longer be used.
It remains to be seen how long this version of LDM keeps working, after new vbulletin versions are released.
