as many may know, I have been nursing (almost to death!) the Common Lisp Document Repository (CDR). Pascal Costanza et al., started the project many years ago and then I sat on top of it for many more.
I finally found some time to work on it and the result is a revamped site (cdr.common-lisp.dev) with the addition of stashing documents in a Zenodo Community (CDR), which has the benefit of producing a DOI for each write-up.
Moreover, Pascal Bourguignon, Michał "phoe" Herda and Didier Verna have agreed to become CDR editors. Many thanks to them.
So, if anyone wants to submit a "specification" for something of interests to the CL community, she/he is most welcome to do so. Just remember that good specifications are not so easy to write.
