Create a sponsor profile:
For your convenience, sponsorship profiles are now managed within the Employers tab of your dashboard. To create a Sponsor, first create a new Employer Profile, and make sure the profile's expiration date is set to "never," by scrolling down to the "Expiration" field and selecting "edit," followed by "never," and "OK."
Then, select the box at the bottom of the Basic Profile page that indicates sponsorship/partner status of the company.
Once this box is checked, the profile will show up under the Sponsors sub tab in the Employer section of the dashboard. From this section, you can make additional edits as necessary.
