Please don't tag me in other topics where I can't answer. As subscribers, our previliges in forum are limited and we are only allowed to post in UG and lab testing sections, so when you initiate a thread and mention me I am not able to comment in your thread, so whenever there a question or a topic, feel free to post about it in this thread, no need to create a seperate one, otherwise you can't get my answer or opinion about it.
