Based on my title and, I am curious to know how many post as newbie are required to post in the forum because I was put so much fear not to post randomly or carelessly.
There's no limit as long as you're able to maintain a quality delivery in whatever thing you're posting about on the forum, the quality is what matters most such that it will contain what others can learn from and be benefited, you should also know that in doing this, it will take you more time to discover about something, understand it and then typed it and post, then you move on to another aspect and do same, i believe you wouldn't want to stay on the forum all day long everyday, this are what can limit the extent to what you can post per day if truly you want to deliver upto expectations.
