Ha, I was just about to say that those posts are possibly copied from somewhere. This is another big issue and what's colossally wrong with this forum and shows you what a sad state of affairs it is. Often when I'm going through threads and and I actually see a post from someone putting some thought and effort into them they stand out like a sore thumb amongst all the spam and one liners, but I have to google them to see if they're plagiarised and sadly probably 7 or 8 times out of ten they are.
Maybe quite off-topic, but what do you think about this site?
