You get out of this site what you put into it. Its not about the posts you make , its how you interact with and take care of the other members here and reply to them on their posts that matters. Some of course are nasty or perverse and you can block them and remove them from your SW experience. You can unblock them anytime you want. But its in your control.
Always remember.... YOU control everything anyone sees or reads about you... If something would embarrass you DONT write or post it... Those that annoy you or upset you... Use the block button...
It really can be. There's def a variety of communities on here, and some you'll probably decide to stay away from. Overall though it's really pretty cool to find like-minded supportive people.
