Writers' Resources Question

Hi. I just wrote a humor piece that’s fiction and 1,700 words. I have contacts at a few publications but I’m trying to get a list of more magazines and websites that publish humor. The major resource I’ve found is the WritersMarket website, but I haven’t signed up for it so I don’t really know what the site contains. I’m wondering if anyone here has used the site and can recommend it. I’m mostly looking for contact info on where to submit my humor piece. Thanks!
