The MyBB HTTP Gateway is a project used by Irix Network to offer a basic, feature-limited HTML version of the website for use on very old browsers. It leverages the MyBB Integrator class.
In order to install, upload the entire classic directory to the root of your MyBB installation.
Then, a custom field (fid6 for irixnet) is added with radio buttons for Yes/No added.
Creating the templates in the top level templates directory will finalize this.
The MyBB Integrator Class (GPLv2) is leveraged for this.
