I made a terms of use field by first inserting html saying, by clicking the checkbox hereunder you confirm accepting our terms of use
then I insert checkbox that is required with text, terms of use. I think that works fine.
I have a multisite network of 5 sites and I can confirm that a created form only works in the site you created it in. I was just looking for a way to copy it to other sites instead of having to create it again. Any ideas?
