Yes. If you've worked with a translator you like, you can add him/her to your "MY Team."
You can subscribe to the MyTeam service and add as many translators as you like.
A My Team translator is the only translator who can access your projects within his/her language pairs and expertise. You can have multiple My Team translators for each language.
Because your My Team translators are the only ones with access to your projects, translation start times may be delayed based on their availability. If you have an urgent project and do not want to wait for a My Team translator to become available, simply click the "Get it Faster" button on the project page and your project will be allocated to all eligible translators.
