Are you going to Lotusphere 2012 and have open PMRs?
Lotusphere is a great time to meet developers and support face to face. So if you have any open PMRs that you want to address at the event, I recommend mentioning this to engineer working that PMR. This way we can inform development/support representatives attending and see if they can arrange time to discuss with you in more detail.
Also when you are at Lotusphere if someone suggests to open a PMR so they can look at it, don’t forget to get their name to add to the PMR! This helps routing it faster.
