I have a few questions regarding functionality testing of PBs in a new wp installation (3.0.4):
Are pingbacks sent immediately when a post is published, or are they scheduled as a cron job? If the later is correct, how often does the job run and can I trigger it manually?
Are there any other terms for PBs to be sent besides having "Attempt to notify any blogs linked to from the article" set to on, and of course a link to another blog in the post content? (for example, should the sender post be public and not private? should the blog be non private?)
Should the outbound link be placed in the post content or can it be placed in a custom field of the post in order for the PB to be sent?
In case PBs are not sent nor received in my blog, what is the best way to debug and detect the problem?
Thanks in advance!
