<h3>Welcome</h3>
We need to add some content here, soon! Anyway, this is kwotes. It's
a chat quote database system, with a twist. This chat quote database
is publicly moderated... so ALL of your submissions are accepted, and
it's up to the general public to determine wether or not it's funny...
no stupid moderators who wouldn't know funny if it grabed them by the
asshole and ripped them apart. Anyway, this system has some advantages
over existing systems, here are a few:
<ul>
<li>
You can vote for a quote without it going to a new page and
you losing your place in your current view.
</li>
<li>
The system is publicly moderated so that all submissions are
accepted, submissions that are less than zero for more than
a certain period of time are removed from the system (maybe...)
</li>
<li>
Users may only submit 4 quotes per hour.
</li>
<li>
The system is opensource, you can download the source code
using the link at the bottom of the page. Work is being
done to setup a CVS repository and such.
</li>
<li>
Slim sleek design... all browsers like us :)
</li>
</ul>
We're thinking about creating an egdrop script for auto submiting
quotes to the system, we'll see how that goes :)
