Sibhusky, you make a good point. However I suspect that most/many people don't even bother searching at all.
At another forum I read often, airliners.net, creating a new thread goes like this:
1. Click "Start New Topic".
2. A form is displayed. To the right of the box where you type the title of the new thread, there is a blue search button. Underneath the box, it says "Please don't post doubles! Use the blue button above."
3. On that same form, more to the right, it says "Check if your post has already been discussed", albeit in a tiny font and kind of buried among other instructions like no hostility, copyright violations, etc.
4. This is the cool part. After filling out that form, there's not a "submit" button, there's a "preview" button. When you hit "preview", it gives you a new page that says "Please make sure you are not posting a double. If this topic has already been discussed you should post in the thread already started. The following similar threads were found:". Then it shows you the top 10 search results generated from what you put as the subject of your new post. The "submit" button is shown below all that.
I think this must really cut down on the number of duplicate posts on that site. It's certainly stopped me a few times. But of course, as we still have "will I get powder at (resort) in (month)?" that forum is still forever plagued with "why doesn't (airline) fly to (city)?", etc. But at least they don't have a hundred different threads all asking "on which airline can I still fly on an L-1011?".
Epicski doesn't have #1, #2, or #3. I'm not sure about #4 - I'm not willing to risk accidentally creating a worthless thread just to test it out, and I don't have anything worthwhile in mind to start a new thread about :) But, perhaps epicski could consider implementing some/all of these things. I'm a web developer myself, so I realize that my suggestion would involve a lot of work (and unfortunately I don't have the time to offer my assistance).
