I wish the Signatures app worked with hyperlinks that way I could integrate my contracts sent for signatures with payments apps like Stripe.
There is a link in the YC SAFE template, one of the most used templates out there, I think. It ensures that the document they are signing is in fact the one recommended by YC.
The agreement is meant to be used without editing so we can't/shouldn't remove it either. Would be nice if it actually worked.
