Ann, you don't need to subscribe to The Washington Post to enter
the invitational. In fact, the newest contest is one that may interest you and others here, since it calls for obit poems about anyone who died during 2018 (up to eight lines).
The WaPo does have a pay wall, however, so you might be cut off after a certain number of page views. One of the ways you can get around that is to cut and paste the URL of the page into an "incognito" window (or whatever your browser calls the sort of window/tab that purges all cookies and trackers). Another way is to join the Facebook group of "Devotees" because the editor, Pat Myers, always posts non-paywall links there. And you can also join the highly-educated Devotees as they make horribly juvenile puns and make fun of other people's poor grasp of grammar and spelling.
The bad news: the only prizes they offer are gag prizes, mostly refrigerator magnets with bad puns on them. But the chance to have your name printed so many times that the required ink could fill a swimming pool makes it all worthwhile.
