There ARE rules however:

• Keep it short. The footer must be small, no greater than ~200px tall in total.
  
  
  
  • The size constraint applies to both text and images.
    
  • Do not cram your footer full of text. If you want to write an essay, do it elsewhere.
  • You can use [imgs] tags to easily make images smaller, like so:
  
  
  Code: [imgs]https://nsmbhd.net/data/logos/logo.png[/imgs]
  ^{Otherwise, you can use HTML or CSS properties (if you know how to use those) to resize content more precisely.}
  


• The footer must be CLEARLY visually separate from the post content.
  
  • You should be able to tell at a glance which part of your posts is the post content and which part is the footer.
  • To aid you with this, you'll find a checkbox labeled "Show signature separator" on the Edit profile page. When enabled, it adds a line separating the post content and the footer.
    It is ticked by default, and you may only untick it if you add a DIFFERENT way to separate the post content and footer.


• Don't put anything offensive, problematic or annoying inside of your footer.


• You'll also notice there's a "header" field above the "footer" one on the Edit profile page. Do NOT put text in there.
  
  • The header is meant for HTML and CSS only; if you do not know how to use those, don't put anything in this field.
