Normally I have several review audits each day. But today I haven't seen one yet.
Is this linked to the birthday date in my profile or is it pure chance?
You posted this just to get happy birthday comments, didn't you? :P
Anyway, there is a 99.99% chance that this is pure coincidence and you can get audits today just like you have the chance of not getting any audits on another day.
My hypothesis is that according to your profile you are 46 years of age so maybe you're approaching that point of life where you did indeed get audits but then they just "slipped your memory"? Be assured this is not ageism and I in 6 to 8 years I expect to be the same. Meanwhile enjoy:
fun
