Since you read the rules Im sure you pretty know what you need to do mate. Just be yourself when posting and always create topic that can contribute to the forum.
There are plenty of newbies here whom always post long narratives and some non sense post. Piece of advise, be short and concise when building up a post, always direct to the point and make sure everyone understand the way you explain something.

Goodluck merits will come un noticed.
