OP, it's been a while since you opened the account, the first thing you need to do is become a forum regular.  The important thing is that if you are in the habit of reading where the senior members of the forum are discussing what topics, what threads they are writing, then I don't think you will have any problem with posting.  If you go from being active in the forum for 2-1 days and then come to the forum after a month or two then everything will become difficult for you, then it will feel like I am learning the hard way.  I say be regular, give it enough time, the more time you give the more you will learn and the later it will seem very simple.
