The service is clearly being pitched to the security conscious.

Mega is also offering bounties for anyone who can find security holes at the moment.

It’s a fledgling beta, but the adventurous can try it out right now.

At the moment, the service is limited to voice (seen above) and video calls.

Text chat and group video conferences are coming later.

The beta is open to the public.

All you should probably do is sign-up for a Mega account at the source link below and add contacts.
