Hello. I have ideas. If you invite me, I will draw a design for you.

Yes, please do.

Until you send an invitation to the artist, it is not possible to upload the drawing. I am not invited now (this "invite" function is available only to the customer, after the invitation, the artist receives a notification on his page) and cannot upload the design.

Not sure how to do that. I clicked on your user name and clicked on invite this artist. Did that work?

No(((

I wrote to the support center. They will explain how to do it.

"Client can invite designers by going to the project's 'invite wizard' button and choosing which designers to invite."
"Should the client need assistance with this, please request him to contact Customer Support so we can assist him."
