So I've been absent from the forum here for quite awhile that I feel really lost! I see some posts regarding a MMv4? (mmcm) I read a few pages back and really dont see any major posts about it. What exactly is up with this new version of MM? What are the advantages/disadvantages? I am currently running MM 2.09.1 or 2 I cant remember which - with kmeaw3.55. I have a WD 1TB MyBook external HDD...I havent had a problem 1 with this, I absolutley love it...However I feel that I am not using the system and or MM to the fullest to get the most of them. Thanks in advance - - EH
