Wrong textdomain in a string

Hi, thanks for the great plugin.

I use it in a Greek installation, so I noticed that on
/bp-activity-subscription-functions.php Line 1380:
__( ‘Posted a Group Notice’, ‘buddypress-docs’ ),

you use a different textdomain ‘buddypress-docs’ instead of the ‘buddypress-group-email-subscription’ which is the plugin’s textdomain.
This prevents the string ‘Posted a Group Notice’ of getting translated.

Can you fix it in the next update, please?
Thanks in advance,
Lena
