HT 30s Rule

Mortenrb

Those who play Hattrick, and are active on the forums, will know what this app is. The app is pretty much just a vizualisation of the 30 second post rule that hattrick has. When you click on the submit button, it will store the time of the submit, and countdown 30 seconds from that time, this way you know when you should be able to post again. There is acutally no need for defining any language for this extension, but Google requires me to do so, so I chose English.
