Deleting Racket (programming language) is harder, so I put in an admin request on this, and carried on editing the PLT Scheme content to refer to Racket. A couple of questions: 1) In sentences such as "DrScheme is a part of PLT Scheme", I'm guessing this should turn into "DrRacket is a part of the Racket project", or something similar. 2) More generally, it appears that "PLT Scheme" should be replaced with "Racket", meaning that the PLT disappears. Yes? 3) The examples on the wikipedia page are utterly loathsome, leaving the reader with the impression that "hello world" requires ten lines of GUI garbage.

I took a look at that page, and our situation (the underlying project was renamed) doesn't seem to fit their criteria, which all have to do with errors in encyclopedization.

[racket-dev] Wikipedia page
I've taken a first crack at creating a Racket (programming language) page in wikipedia, simply by copying the first few chunks of the PLT Scheme page. This is a bit experimental, because it may be that Wikipedia has an existing mechanism for renaming, so I figured I'd just spend five minutes on it and wait for Wikipedia admins to tell me if I'm doing something redundant. FWIW, there's also a DrScheme page to update and presumably a whole pile of references to PLT scheme, membership in various categories, etc. John smime.p7s Description: S/MIME cryptographic signature _ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev
