Christopher's fund needed a paypal button, easy I thought, but then I realised just how many different parameters would be needed for the tag.

I tried a number of different ways of approaching this and settled on allowing people to create their own paypal "tags" by saving the HTML and being able to reference it with a simple tag.

It has been asked, "why can't you just let people enter HTML", well as the system is designed for multiple users, and for collaberative sites, allowing HTML would be somewhat of a security risk. With this method only trusted administrators of your site can define "special" tags with this new method. I will be looking at extending it for more flexibility in the future.
