If your online community is a "labor of love," or perhaps for a non-profit or charitable cause, you can collect donations (either one-time or ongoing) by using a Paypal widget.

Hoop.la makes it easy to add custom widgets, so all you need to do is go to the Paypal site and follow the instructions.

How to Set up a Paypal Widget on Your Hoop.la Community

1. Go to Paypal and create your desired button (be sure you read the instructions regarding which type of button you need). 
2. Copy the widget code (and save it somewhere).
3. Go to your Hoop.la site, and on the page where you want the widget to appear, click "add widget to this page."
4. On the widget popup, select Create New Custom Widget.
5. In the popup, give your new widget a name, and paste the Paypal widget code into the larger box. Click Create Custom Widget.
6. Drag the new widget into position on the page wherever you want it to appear.

Note that you can also put the Donate button in your header, footer, or on a custom page within Hoop.la as well.
