English to Dutch Social Sciences Computers (general) social networking terms

This term is used in an explanation about how to send messages on a website. The full context is:

The send message pop up box opens. You can add additional people to your message by typing their name or by clicking the 'Select People' link. Type your message in the message field. You can upload a photo or at mention people in your community. Click the 'Send' button.

I found an explanation in English. i.e. "@ mention; a convention of various online communication media wherein typing an "at" symbol (@) directly before another person's name or username either alerts them they've been referenced in a message, and/or makes their name into a hyperlink." But how do you say this in Dutch?
