There is an edit button, you know.
In your defense, though, you need to have 20 posts before you are allowed to post links (this includes pictures, as you might understand). So have a look around the forums, join the conversation if you feel that you can contribute (if you use proper spelling and grammar, and post well thought-out posts instead of one-liners, people will be a lot nicer back!), and come back once you've reached that magical number.
