Duotrope is a great way to find submission calls and publications open to submission. I think the membership is like $5/month but they will give you a week or two for free. This is an awesome place to find submissions for flash fiction in some genres, less so with romance. But we talked about articles earlier this month, and it can be a good place to find a fit for your article or even submission calls looking for articles.
