Here's the thing I tell my guys. My MEB/PEB is good as a resource for AR's and other helpful information. What it isn't going to help you with is anything of substance. Why? Because the information in it is added by your PEBLO. Your case was uploaded to the PEB in December 2012. Nothing has happened on it since that the PEBLO added, except for a minor update, hence the date last change made in May of this year. The reality of it is there is nothing for a PEBLO to add to the My MEB/PEB tabs until the PEB/VA do something and then it should be old news when you look because your PEBLO should be talking to you regularly.
Since we know the case was uploaded to the PEB, your PEBLO can easily check the Transaction History tab in ePEB. In that, he can see what has been done and exactly when. There is also a tab on that to print the results. Tell him you want a copy of that tab.
