How can I change my specialization and category?

To do this, go to your profile settings and find the «Specializations and skills» section. There, click on the drop-down list of Specializations and select the new specialization in which you want to work.

Owners of free accounts can specify only one «Main specialization».

You can expand your capabilities by buying a «Pro» account. You can do this in the «Paid Services» section. Owners of extended accounts can choose several Specializations.
