Disclaimer: I'm an old dude and clearly not in your target market.

I am a graphic designer, though, and based on my experience, nobody--not even cutting-edge, next-generation people--likes to read whole sentences or paragraphs in all caps, so I'd advise against B, C, and D.

E and F are fine for a logo, but too hard to read for a whole sentence or paragraph. But maybe that's the effect you're aiming for: something that looks like a secret code that only the cool kids can read, and their parents (me) can't read.

Another vote against all caps; it's okay for a few words but it's hard to read sentences/paragraphs set that way.

Sounds like a job for…Bank Gothic!

> emails, text

Won't work. Emails and texts use fonts the recipients have on their computers/tablets/phones. If you use an unusual font which those folks don't have, it will appear in a different font on their devices.

An alternative for email might be to send the message as a graphic or PDF to preserve the fonts and appearance. Keep in mind that some folks (mostly on cell phones or tablets using data plans) don't download graphics automatically so they won't go over their bandwidth allotment, which may reduce readership.

Another option is to include a link to a web page.
