Script: Rotate To ID [JS]

Important!

Dear visitors,

This blog and the Tigarus.com network will be changing our website software in May (2024). There will be some down time and there will be a change to the webpage addresses.

We will also be removing the Anime blogs. The Rocksmith Songs website will be unavailable of a few weeks or months while I move the database to the new software.

At the moment we are running on Wordpress, the new software is an in-house project which is 57 times faster. It will also provide more freedom for development.

Thank you for understanding.
