@yawar20, @gulu_khan, when a thread is opened it is because any user can comment or ask if they have any questions. We are all users, no one is superior to anyone else and we all have the same obligations in the forum, to comply with the rules and create a good environment to discuss anything. No problem if users post here. Nobody should be "afraid" to answer, ask questions or participate, that is the essence of any forum and what this community needs.
