@foxhound:
	The rights for pages are actually all in the sed_auth table..
	I quickly looked:
	`sed_auth` (`auth_id`, `auth_groupid`, `auth_code`, `auth_option`, `auth_rights`, `auth_rights_lock`, `auth_setbyuserid`)
	 
	You probably need to unlock the group by changing the auth_rights_lock value...
	And then you can probably change the rights via the admin panel....
	The default grp_id for guests is '1'...
	So try to change that auth_rights_lock for 1 article category and see if your red cross for the 'W' part dissapear in admin panel.
	ow yeah its binary so calculate the new value by using this:
	    $mn['R'] = 1;
	    $mn['W'] = 2;
	    $mn['1'] = 4;
	    $mn['2'] = 8;
	    $mn['3'] = 16;
	    $mn['4'] = 32;
	    $mn['5'] = 64;
	    $mn['A'] = 128;
	you prob need to clear bit 'W' so substract 2 from the value in the database !
	By the way,,, i havent looked where the default locking for pages come from... yet...
	 
	Small update on the locking.... i found it..
	It is HARDCODED inside a function to make new pagecategories locked...
	its in functions.admin.php look for function called: sed_structure_newcat
	look at this bit:
	               if ($v['id']==1)
	                {
	                    $ins_auth = 5;
	                    $ins_lock = 250;
	                }
	That is your default locking (red crosses thing.... in admin panel) change $ins_lock value (prob to 248) and new cats can be unlocked for guests to WRITE ub.
Good luck !
	 
	p.s. I couldnt believe that this is hardcoded.... not very friendly
