I've successfully installed your product and have successfully added GLSL! Yay! Thank you.
I have one issue though: We use the fancy editor in vBulletin, and once we add the tags--for any code block-- and preview or save the post, the tags are removed and the code is saved as converted already into its fancy format. If we come back to edit the code, and save, our code is all smushed up onto one line.
Is there a way to have the tags remain in our posts and not get converted, much like how the normal BB Code tags work?
Thank you.
