How do I find the external URL so a customer can look direct at my gig?
If you click on your user name in the upper right hand corner of your screen you will be taken to a page that displays all of your profile and all of your gigs. You can simply copy and paste that URL
If you want to send one gig in particular you would then scroll down and click on the desired gig, then copy and paste that URL.
Best of luck!
