Nice job, Janet.
Personally, I like the all caps. It might be "shouting" in e-mails or posts, but I don't personally care for the popped up look of raised lower case letters. Your solution solves that but, again, just my opinion, it make the letter look kind of funny.
I feel like a real renegade saying that. I know this forum is mostly about bragging an receiving praise. Nothing wrong with that for sure because it encourages which is a good thing. But you asked the question so I am assuming that you want real answers about what people think.
I hope I didn't offend as that is not my intent at all. I'm glad you tried it the way you did so I/we can see what it looks like (for whatever that's worth).
