Ticksy wordpress/php script



I am looking for a PHP script or WordPress clone of Ticksy.com. Let people sign up using a sub-domain or /domain approach and pay a monthly subscription fee.



I am also almost decided to use Ticksy as support forum (I don’t have one yet)
Could someone please share a link to their support forum using Ticksy?
I would like to see a live example before buying a subscription to them.
