No personal fight here, I was simply pointing out what the rules of the forum are and hinting to you why no one had bothered to answer.
For one reason or another 57 people viewed this thread, yet only one answered. Since it's a pretty simple question, It's likely that no one else answered because it was easy to find out for yourself, (a google search of the forums for .cbr turns up several answers and a full google turns up hundreds). It happens, things slide off the frontpage, people choose not to answer.
By bumping you're insisting on an answer from them, pushing yourself back to the front of the list. If the forum allowed bumping the front page would fill up with those requests, every one of them demanding me me me. At that point, the people who do go out of their way to help people with complex questions get turned off because they have to wade through all the bumps.
As I said, nothing personal, the forum just works better without bumps.
