This is about the team request notification which team administrator receives.

It says:
"User requested to join your team
XXX has requested to join the team YYY.
Congratulations! Your application to join the team has been approved. You are now a member of the team YYY."

Obviously the last sentence (COM_EASYBLOG_NOTIFICATION_TEAM_REQUEST_APPROVED) is incorrectly included here.

Hope you will fix it. (although I know email template can be customized.)

Thanks,
