ClickBOOM have recently put a small question on their webpage asking simply if people have a PPC card or not. To reply to it you will need something called a BOOM#, this is a special number that all people who have registered will have.
If you do not have a BOOM# you can apply for one online. I can omly see this as a good thing, I assume clickBOOM are trying to find out what number of their registered users actually have a PPC. With the help of the PPC Quake petition which will be sent to clickBOOM and this maybe we will see PPC Quake in the not too distant future.
The PPC question is in the 'Attention' part on the main page, make sure you go there and fill it out. Their webpage is at www.clickboom.com as if you didn't already know ;).
