perhaps we need to quote Patio's explanation a few more times...
It's been the same since Carbon was appointed.
It's been the same since Carbon was appointed.
It's been the same since Carbon was appointed.
And it couldn't have remained the same since Calum was appointed. Otherwise Carbon wouldn't be on the list!
Name: Calum
Start Date: October 06, 2006
Name: Carbon
Start Date: February 07, 2007
Look CAREFULLY at the dates. Calum started first. Now, logic dictates, that if it was the case that Patio "meant" calum (which he didn't, chances are if he did, he would have SAID calum, too which I would be explaining this to him, albiet with less drawn out logic), that Carbon would not be present on the list. However, Observation concludes that indeed, Carbon is on the list, his join date is AFTER Calum, and thusly it must have been changed since Calum started.
