Hey let me give you some advice for doing these things. So your on a forum. A very very good forum that many people come and chat on. Now you come here to make quality posts that help you and the viewers. So if you say "Make sure to subscribe" that is kind of advertising yourself don't you think? Forums are not for that. So try making quality posts and interact with the people here. It will gain you respect and subs. Try it trust me.
