You can raise money for yourself, your groups, or other individuals or groups on the Action Network. As described here, the first time you create a fundraising or ticketed event page you'll be asked to create and connect a WePay account. The same goes for groups you are an administrator of -- the first time you try to add them on a fundraising or ticketed event page, you'll be asked to link your previously created WePay account to this group. You must link your group to an individual WePay account connected to your Action Network account -- you'll log in with that account later to retrieve both donations to you as well as donations to your group (separated out in different buckets, of course). If you do not want to be the WePay account associated with that group's fundraising and you'd rather a different administrator handle that, have them create the fundraising or ticketed event page the first time and link to their account.
You can also search for other individuals or groups who have set up their WePay accounts using the bottom section of the fundraising or ticketed event recipient addition window. If a group or individual does not appear, they have not set up their WePay account yet and thus are not eligible to receive funds.
Note: You must enter bank details within 30 days, otherwise you won't be able to raise further money on your fundraising or ticketed event pages until you do. You also must have a US Social Security number or Tax ID number to raise money via WePay.
