Use *, †, ‡, §, ◊, Δ for all legal disclaimers, in that order - do not use superscripted numbers for legal disclaimers.
Put disclaimers at end of the section which references that disclaimer instead of at the bottom of the page - exceptions to this are if a disclaimer is used in more than one block, then use same symbol on each instance but put disclaimer at bottom of page, or if a disclaimer is long enough that it doesn't look good in the block itself then it can go at the bottom of the page.
Use superscripted numbers for source material references, such as for claims like "97% would recommend Omnipod to a friend".
Source material references can go at the bottom of the page.
For both the icons for legal disclaimers and the numbers for source material references, use the superscript tool in the WYSIWYG toolbar.
