Sometimes I get some crazy ideas for websites that I think would work out pretty good. I always want to make things free w/ paid additions to the free service (but still have other ways for free users to receive the additions, with a little work). This way, more people would use it. If it got to the point where any certain site became -huge- then it might be a good idea to charge a lifetime membership fee of $5 per user w/ advanced features, and then have there be additional -cheap- paid additions for those who are looking for less work and more outcome.
It seems that most of my ideas (some of you probably have noticed this) are based around -unique- ways to advertise your site, things that I havn't heard of yet. I think I have figured out a good idea for another website, that would be a pretty unique way to advertise your website.

The above image is a collaboration of what are called "userbars", generally used by people to put in their forum signatures (and sometimes websites). They usually contain just information regarding the user, ect - this is to save space in forum signatures and loading time on forums and alot of people feel they just look nicer than big bulky signatures.
My idea?
Users can sign up for free. They sign up with a website and an image of a userbar (there will also be a downloadable program for users to easily create their own custom userbars). The image will have to follow exact dimensions, to ensure fair advertising. They enter some information and they get 1 free ad (IE 1 userbar). Users upload it and it is immediately entered into the ad database.
The user then receives a unique code in both HTML and BBC (I think that's what forum code is called hehe). This code will just be an image link which will link to say http://www.WebsiteName.com/clickthrough.php?id=#### where #### is the users ID. The image will simply be http://www.WebsiteName.com/current-ad-image.jpg.
Now... The "Current-Ad-Image.jpg" will automatically be changed every X minutes (probably 1 minute) via a server-side program which will go into the website and run a script that will change both the image and the current click-through ad...
So basically.. If I had it in my signature, it could show an ad for Google.
The userbar would be a Google ad. It would link to http://www.websitename.com/clickthrough.php?id=1 - But when you click it, it will take you straight to google.
Say you go back exactly 60 seconds later - It will now be an ad for Yahoo.
The userbar would be a Yahoo ad. It would STILL link to the SAME link, but when you click it, it will take you straight to Yahoo.
Get the point?
Now... To make it fair, so people couldn't just sign up and never place an ad on their forum signatures, and be receiving free ad-space, it would work like this...
For every time somebody clicks a userbar in YOUR signature, it would give you say.. 10 points.
Points can be used to do multiple things:
(these are example point pricing, will probably vary, but just for information purposes).
1) Add Another Month Of Advertising = 50 points (or 5 clicks).
2) Add Another Userbar Ad = 200 points (20 clicks).
3) Have X Ad Seen More Frequently = 500 points (50 clicks).
Ect, ect - Maybe have a section to advertise on the website itself through rotating text link for 100 points, or something.
Now, for people just looking to advertise, they can just pay for points.. Lets say... $0.01 / point.
So they get 1 Free Ad upon signing up. After 1 month, they would need to pay $0.50 for another month of service.. Obviously, that's not unreasonable at all. If they want to ad another userbar to the rotation, they would pay $2. If they want a certain ad to be seen more frequently they would need to pay $5.
All clicks would be registered once PER MONTH by IP Address - therefore resulting in only 1 unique click (per each account) per month. At the end of each month, IP's will be reset. This means that if you have the userbar in YOUR signature, a person can only click it ONCE (despite the ad) to give you 10 points. So if they click it every minute on your signature for a whole hour, you would only get 10 points, not 600.
But if they go happen across a different user and click on their signature because they're interested, that user would receive the point also.
I know it sounds kind of confusing, but I wanted feedback on the idea. I know it has it's ups and downs, but I think it's a pretty unique idea, and with forums being a huge thing now-adays, I think people would get alot of exposure.
