Font Families in Rise
There are just 8 fonts available in Rise to choose from, unless you upload your own. The problem with this is with government agencies (FEMA, FAA, TSA, etc) with IT departments that are back in the stone age which only allow IE11 and have Font Downloads turned off - meaning any .woff fonts are blocked and IE11 substitutes some really awful fonts in their place.
The easy workaround for this is to add fallback fonts to the css rules for font families. Instead of just "font-family: Open Sans", you should also include additional standard fonts like "font-family: Open Sans,Helvetica,Arial,sans-serif"
Please consider this for a release soon, otherwise these agencies are stuck with some truly awful interfaces.
