New to Typophile? Accounts are free, and easy to set up.
In an effort to see what the wiki's like, I added entries for Rudolf Koch and schaftstiefelgrotesk types, as well as filling out the entry for blackletter. I have no doubt that others are going to want to rework what I did, as I mostly concentrated on the historical aspects of blackletter I find most interesting, but I thought I'd get the ball rolling.
Funnily enough, there's not yet a category in the wiki for typefaces.
