recommend a plugin for sticky posts

I'm using a multisite installation with the latest version of WP. I'd like to be able to make some posts in some categories sticky. I've searched your plugins and can't find one for this. I've tried searching other plugins but can't find one that says it's been tested on my version of WP. I installed the "Category Sticky Post" plugin to try it anyway and it installed at the network level but doesn't show up in my sub sites plugins list. Can you recommend a plugin?
