Not possible in 1.10.x but it was added in 2.2.x.

Actually it might be possible. You can try editing skins/_atom/_main.php and adding your own post count around line 66:

			<updated><?php $MainList->mod_date( 'isoZ', true ) ?></updated>
			<?php
			$posts = 24; // adding this line MIGHT work ;)
			while( $Item = & $MainList->get_item() )
			{

(The line number will probably change for each flavor of feed, but the same "while MainList get_item" should be there.)

Much easier in 2.2.0 though. Just tell it how many via the back office.

Thanks it did not do exactly what i wanted. I'm not too good at coding so maybe it was me as well. I'll just have to live with it the way I'm doing it, maybe I'll split the difference at 12 :-/ .

I'm new at Bloging and B2 and I wanted to start with a stable version thus 1.10.

this may or may not work

copy and paste the following into notepad and save it as hacks.php, then upload it to your /conf/ folder

<?php
if( isset( $tempskin ) && substr( $tempskin, 0, 1 ) == '_' ) $posts = 20; // change number to suit
?>
