Matt,
I am sorry that you had a slow response from Support for your question. You should be able to change the funds to support Online giving by going to the Giving tab, opening the Designations menu, and Choosing Add/Edit Funds. From there, you can edit your Funds to support online giving by choosing the "Web-Enabled" option. If you have Sub-Funds or Pledge Drives that you want to enable for online giving, you can also enable the desired Sub-Funds or Pledge Drives.
If you are not able to see those, then you may need the specific rights within F1 to make these changes. Your F1 administrator can change that for you if necessary.
In Him,
-Peter Schott
