There's really no need to post a public apology for issues that no one else is aware of. It's more important that you simply try to follow the board guidelines. If you've truly learned, your posts and actions will speak for themselves. I'd like to point out, though, that the staff members on this board who are known as experts have gained that respect due to the work they've done over time, not by coming in and proclaiming themselves to be knowledgeable. You could learn a lot by watching how our most respected members act and post and following their example.
