It was friendly advice (as was the answer to your question). Before you get your feathers ruffled you may want to spend some time reading the forums and seeing how folks here operate. It's a great place with a HUGE body of people full of knowledge. On second thought I should have sent a PM instead of posting to the thread...
In any case:
Like I said, it's (self bumping) frowned upon by most forum members (here and at any forum). I think you will find that this advice is some of the most basic "forum etiquette" you could observe.
Look at it this way:
If nobody responed, that means that those who saw the post did not know the answer, did not want to answer, or had not seen the post yet.
The good part:
You may want to know that most folks here subscribe to the forums that they are interested in. When they log in, they go back through all of the new/unread posts in those forums and respond to the posts they are interested in, no matter what page they are on. Bumping your own post to keep it on page one after 20 mins only servers to:
1) indicate your impatience (and/or lack of common forum etiquette)
2) make it appear that somebody has already attended to your post. Like I said when a post has 0 replies, more poeple are apt to look at it and reply to help out. Once the thread has replies, many uninterested, but otherwise helpful people will simply pass it by THINKING ANOTHER HAS ALREADY HELPED.
3) push other posts (from other patient people) further down due to YOUR impatience.
My post was only inteneded to help you out. Welcome to RC and enjoy yourself.
