You broke a very fundamental rule with the review my stuff area. Never ever ask people to sub you when you are supposed to be asking for legitimate feedback. Everyone on here has a channel of their own and are very capable of understanding that they can sub you by hitting the sub button. By adding the sub request at the end, you take away from anything you might have been genuinely asking prior to that point. Now this just looks like your advertising and anyone who would give you a legitimate feedback will probably just ignore you from now on, or until they forget about this thread...
Not trying to be mean even though it sound mean... Just giving you feedback, its just not feedback with what you were asking for, just some feedback on how to utilize a forum like this to give yourself the most help in growing your channel. Have a nice day.
