The 'Add a Link' form and 'Modify a Link' form are nearly identical, but users are currently requested to pay only for adding links. I would like to be able to request users optionally pay when modifying a link as well. The idea being that a paid modification would appear quickly (automatically if possible) on the site, whereas a free modification would happen "whenever the webmaster gets around to it". Is there a semi-easy way to do this?

best,
