My b2evolution Version: 2.x

Just bumped into this. Not sure if it is covered anywhere already, so here you go.

You can change the default stuff that shows up when you create a new blog by editing /inc/collections/model/_collsettings.class.php beginning around line 47. Here it is, slightly modified to almost fit your screen

var $_defaults = array(
	'new_feedback_status'    => 'draft',     // 'draft', 'published' or 'deprecated'

	'rss2_redirect'          => '',
	);

So for example let's say you added the [url=http://www.leeturner.org/twitterlution.php]twitterlution[/url] plugin to your 247 blog and want it to be there when you create a new blog. It's not by default, so you add the code for that plugin (evo_twitter) to one line here and you're done - no more remembering to go check that box.

'ping_plugins'           => 'ping_pingomatic,ping_b2evonet,evo_twitter', // ping plugin codes, separated by comma

no preview button in this forum in this skin - bummer :(

EDIT: this is also a great place to permanently get rid of rsspam

'xml_item_footer_text'   => '',

;)
