Christ followers can meet together for the purpose of encouraging each other:

at work

at school

at a backyard barbecue

in a neighborhood

in a home

in a church building

in a theater

in a school

in a business

on Facebook

on Twitter

on Internet church

...the list goes on and on.

The focus is not on where and how.  The focus is on meeting together as Christ followers for the purpose of encouragement.

How frequent?  Often.

How do we know this?

And let us not neglect our meeting together, as some people do, but encourage one another, especially now that the day of his return is drawing near. ~ Hebrews 10:25, NLT

Know that you are loved,
