Project requirement and ban words

[razu55]

Hello everyone.
I hope you are all fine in this current situation.

I want to know something. It’s a common question.

1. some times we need to collect buyer email addresses for some configuration. Can I put the “Email requirement” field on my gig? or how?
2. and also need to talk “payment” word with a buyer for payment integration on their website.

But Fiverr policy does not allow like those many more words.
So what can I do? Or how do you all manage those topics?
