Then you need to tell them to be on the computer researching stuff.
You are new on here, so let me break it down for you: Use the search function, it will answer most of the questions you have. If, after searching you still can't find an answer, post up. If you want professional advice, go pay someone for it. There are lots of members here that will help you out as we have lots of others, (just like we were helped) but when you (or your friends) clearly have no clue what you are talking about, it makes it difficult to give you good answers. Again, I'm not trying to be a d!ck here, but some of your posts are questions could have been answered by using the search function.
