interested in participating your project, could you possibly send invitation to me by clicking invite button on my profile?

I don't see an invite button, and when I say I want to work with you, it starts process of adding a new project. Is it required for me to invite you for you to submit your designs?

i can't participate without invitation, and we also can work on by 1on1 project in this platform.

Extend and'll get into it into24hrs. Thanks
