Shan, I think it is lame (not good) to have predictions by others posted in this way. If your friend wants to post predictions here, he/she should get a login and post directly. Then, if someone wants to ask a question, they can do it directly. If you are claiming that something you posted for him/her was a success, you should have a post where you paste in the prediction made on this page, and the results. I have not been impressed with predictions that have sliding time windows...they will eventually be correct.
