Hi Nick,
Nice summary.
Here are some corrections for some sites:
* chicken.wiki.br is not used anymore. Now we have wiki.call-cc.org. Basically all the “official” Chicken services are under the ca-cc.org domain. Chickadee is api.call-cc.org, wiki is wiki.call-cc.org, pasting is paste.call-cc.org, code is code.call-cc.org, bug tracking system is bugs.call-cc.org, the main page is http://www.call-cc.org. The egg index can be found at wiki.call-cc.org/egg-index
* The search service at callcc.org is seriously outdated. api.call-cc.org should be used instead.
Best wishes.
Mario
Hi Mario,
Thanks for taking the time to read this post and provide suggestions. I’ve made changes to both this page and my personal Chicken bookmarks. I appreciate the corrections very much! If you happen to see any other errors please drop me a note.
