sticky post

I’m not sure of the built-in mechanics of a sticky post, but I know how I would do it if I had to do it from scratch:

I’d add a custom checkbox field named “is_sticky” or some such and check the posts I wanted to stick. Then in the template file, I would use 2 queries/loops: the first to retrieve posts with is_sticky=1, the 2nd (normal) to retrieve posts where is_sticky=0.
