Like Eelco said, it was just a matter of bad timing. We had another thread on the same exact subject that I locked because it had pretty much run its course. Your thread was locked (not by me, but by another moderator) because it was about the same thing that the other thread was about.
Don't be offended, and keep on posting. Nothing personal regarding locking your topic... it was just a coincidence that you posted the same thing that we had just locked.
