At the time of writing this, it is set up to hide the
[code]BBCode from non-donors in forums with donor-only extensions, and instead show a replacement message, customizable in the ACP. For example, visiting this post as a guest or normal user, you won't be able to see the actual contents of the
[code]BBCode: viewtopic.php?p=163#p163 I might do further experiments down the road and extend this to other/new BBCodes.
As it's in early development stage, bugs are pretty likely to surface. If you find a post where you think you can't see a BBCode even though you are supposed to, or vice versa, please let me know so that I can look into it.
