I'm trying to write a few extensions to modify the behavior of signatures without modifying posts, forum descriptions, etc. I'd like the modify their behavior in the following ways:
1) If a signature is over X lines, hide it behind a "Show" button.
2) Do not render certain BBCodes.
The problem I'm running into is that I cannot see any way to determine the source of the content in either the core.text_formatter_s9e_render_before
Is this the correct approach? Is what I am trying to do possible without modifying the core codebase?
Thanks in advance!
