Translation BuddyPress,, membership


WP MU environment is hosted on
(Bitnami install on Windows 2012 hosted in Azure)
BodyPress installed
Event Manager plugin is used
Membership WPMUDEV

I have the following questions.:

- Translation into Hungarian (later to other languages)
* how can I manage translation of WPMU sites
* how can I translate BuddyPress
* how can I translate

- Do you know about any other website that uses these functionalities
- I decided to use instead of Events+ any comment on that

Thank you!
