Several poetry forms await recognition on this site, a few being ~
Constanza (invented by Connie Marcum Wong)
Swap Quatrain
Rondine
Quietus (I've written several hundred and so have others)
I'm sure there are many more ...
it helps to classify a Rondine as a Rondine and not a Rondeau and the same for other poetry forms as well, which are being regularly employed. Perhaps PS team should work on this.
