Nice to use. Great looking form. The Pro version is well worth the 10 dollars it costs - think of it as a donation with benefits.
The free version has a link back to Visual Form Builder in the success email's footer. The Pro version offers a quick way to remove it.
The Pro version has extra features. The success email settings are fantastic.
Would be great to be able to remove or change the spam catcher. Maybe a future release will have the option.
Go with VFB Pro instead of Gravity Forms (GF has a nag message in its email footer when your licence expires). Tried Ninja Forms but it's full of bugs. Tried other form plugins but they just don't have the features Visual Form Builder does.
Great plugin. Thank you Mr/Ms. Developer.
