addtag: Whether to add a tag for the group nickname for every group post

oembed
--------
oEmbed endpoint for multimedia attachments (links in posts). Will also
work as 'oohembed' for backwards compatibility.
endpoint: oohembed endpoint using http://oohembed.com/ software. Defaults to
'http://oohembed.com/oohembed/'.
order: Array of methods to check for OEmbed data. Methods include 'built-in'
(use a built-in function to simulate oEmbed for some sites),
'well-known' (use well-known public oEmbed endpoints),
'discovery' (discover using <link> headers in HTML), 'service' (use
a third-party service, like oohembed or embed.ly. Default is
array('built-in', 'well-known', 'service', 'discovery'). Note that very
few sites implement oEmbed; 'discovery' is going to fail 99% of the
time.

oembed
--------
oEmbed endpoint for multimedia attachments (links in posts). Will also
work as 'oohembed' for backwards compatibility.
endpoint: oohembed endpoint using http://oohembed.com/ software. Defaults to
'http://oohembed.com/oohembed/'.
order: Array of methods to check for OEmbed data. Methods include 'built-in'
(use a built-in function to simulate oEmbed for some sites),
'well-known' (use well-known public oEmbed endpoints),
'discovery' (discover using <link> headers in HTML), 'service' (use
a third-party service, like oohembed or embed.ly. Default is
array('built-in', 'well-known', 'service', 'discovery'). Note that very
few sites implement oEmbed; 'discovery' is going to fail 99% of the
time.
