I'm curious, why v3Arcade isn't in premium support. It's hack thread is huge, 100's of pages. It also has nearly twice the installs of ibPro Arcade which is in premium support.
A premium support forum has to be requested via pm from the author to one of the administrators. If the author has not done this, then a premium support forum will not be created. The author is also responsible for providing the support in that forum, which requires regular and frequent visits to the site.
