Hello again,
Thanks for your answer. I had absolutely no idea that Profil was related to custom British sign lettering. However, if I click on the link it takes me to a Twitter post made by Twitter user Ray Newman, known in Twitter by his moniker MrRayNewman. There is yet another link in the message that seems to take one to the Fonts in Use website. However, if I click on that link, nothing happens.
Does anyone knkow why?
