So here I use skeleton theme http://themes.simplethemes.com/skeleton/
It said it support bbpress and jogloshop. And then I tried to use this plugin.
I haven't try it on online server, I tried it on xampp on my ubuntu.
The achievement page is working good. It list all of the achievement and everyone who have unlocked it. But, the link for per user achievement is not working and give me "page not found" page (both from the announcement link or from the wordpress bar).
The acviement I build was some "awards" type of achievement and I gave it manually from the admin page.
thanks for the help.
