This is Lucida Bright. She's very happy to meet you. You put her in just like any other font, but only the ones in the dropdown (Microsoft's 'core fonts for the web') can be guaranteed to appear for all users. You can also safely use Tahoma, because nearly every Linux user will also have it or something closely equivalent.
I'm hoping to include Webfont support to support open source fonts with the new CMS. We'll see how that goes, however. It's a periphery concern, but it would be nice to see some fonts like the Libertine and SIL's fonts some more love.
Thanks for both the tips and links Vekseid!
And I do understand how and why things like this take back seat priority especially when you consider the scope of tasks required to keep Elliquiy running as beautifully as she does.
I know this is going off on a tangent slightly.... But I just wanted to say that I think the spell check function Elliquiy has is by far one of the best I've ever come across.
