Remember also that some of us are posting at work where most of the sites that people link are blocked. Also, I konw I am guilty of asking repeat questions but only because I don't always have time to search at work and don't always have access to a computer at home(I play on the X-box). Lets not forget, the purpose of this site is supposed to be a informative site where players can get better answers to their questions than at some of the other sites. Instead of getting on someone for asking something why dont we just answer what they are asking.
Remember, everyone was a noob at somepoint and just because a lot of people have already asked how to do it, does not mean everyone knows what they have to do.
A solution to this problem would be to make a link for the most common questions and make it so it is broken down by subject(make it easier for people to find some of the info that was already discussed.
Lastly, just because something has been discussed already doesn't mean that it cant be brought up again. Doesn't it?
