Hi @themanualbot if you want to receive delegation you can create an order by clicking here https://www.minnowbooster.net/lease or on this menu item:

If you are a delegator and want to fill leases you can go to the market and click on Fill this Offernext to the lease you choose to fill:

There isn't currently a way to delegators to out in offers, but they can fill existing lease requests as per above.
