I actually kind of agree with Roosevelt. I don't think he was trying to 'own' the forum. Just making a cogent suggestion. Perhaps if you read the other threads, you could ask a question in one of them, or refocus your questions here. It's a good practice to search on your questions and explore what is already out there. It just helps not to cover the same ground, good net-equite (I spelled that wrong). Not a problem if you don't think so though. Just my opinion.
