i have found a page where they have implemented, the link : www.bombastic24.de
i think they user community builder and they should public that add-on for free as they use community builder without paying for it. what do you think about it?
i asked them to public it but they wont, they told me that they have been implementing it for long time. and my answer was, do you think the cretors of CB did it in few hours? it took them longer to do something cool like CB! i hate those developers that use free things and implement something new and do not publish it!!! ARGGGGG!!!!!!!!
