[Plugin: Promotion Slider] Feed limits

The shortcode supports a ‘numberposts’ attribute, like this:

[promoslider numberposts=”4″]

Is that what you need or did you actually need to limit the number in a feed, not the slider?

Hi,
I’d need the number of feed, not slider. Everyday I want to show just 8 news (promotions) per day.
In wordpress you can set all the posts (general settings->reading), but promotions work in another way.
