There’s some great free events out there; SQLBits community day and the upcoming SQL In The City day by Red Gate are just two examples. With the high demand for spaces at events like these, it is well worth getting in there ASAP to reserve your space before they all go and you end up on a waiting list.
But if you find you can no longer make it, make someone else’s day by cancelling your place so that it can be freed up for those on the waiting list. You may not personally be losing out by not taking the time to cancel your place, but someone else will be.
So….“if you can’t make it, untake it”
P.S. Yes, I know, not my greatest blog title ever…
