Im am working with the Opt-in Email module in a project. I can select the preferred font type, using the Rich-Text editor, in the messages that appear in the Opt-in module (I am using Arial), but it appears that the fonts that are fixed in labels, such as "First name", "Last name", "email address", etc. and only appear as TimesNewRoman by default. Do you know how to change this so they appear as Arial as well (or other font type I choose to use in the Rich Text Editor). Do I need a stylesheet for this purpose?

Thanks,
Olafur
