Q:  Is it necessary to register at the Striking...

A:  Any question that comes from someone who has purchased a copy of Striking should be asked at our support forum.

We used to answer questions both here at Themeforest, and at the forum, and we ceased this dual support some time ago. The Comment pages at Themeforest are not searchable and we found that many questions were being asked repeatedly as a result. Our support forum is searchable, which results in a better experience for users, and improves our ability to provide timely support by not wasting time answering the same question over and over again.

So only prospective purchasers should ask a question at Themeforest. Everyone else > the Striking Support Forum!
