Not about this forum, but the main site.
Following the Documentation link on jquery.com leads to docs.jquery.com which has various API REFERENCE links on the left. However, on the right it says "The references on docs.jquery.com are obsolete." It also seems that some of the links on the left do redirect to api and others don't. Probably, because for the others there's no content yet on api.
If possible, please make this less confusing in the near future.
