ワードプレス6と完全互換- I'm not a developer and had trouble registering my plugin so I could update it. The team at HTMLPIE were fantastic. They gave me step-by-step directions and it worked perfectly! The interface to create the forms is a little difficult for me, but I was able to figure it out and am sure if I had issues, they'd be there to walk me through it. I've used so called, drag n drop form plug-ins, but this is my preference.
