 Support
 --------
 
 - If you have any questions about GitBucket, see [Wiki](https://github.com/gitbucket/gitbucket/wiki) and check issues whether there is a same question or request in the past.
 - If you can't find same question and report, send it to [gitter room](https://gitter.im/gitbucket/gitbucket) before raising an issue.
-- We can also provide support in Japanese other than English at [gitter room for Japanese](https://gitter.im/gitbucket/gitbucket_ja).
-- Write an issue in English. At least, write subject in English.
 - The highest priority of GitBucket is the ease of installation and API compatibility with GitHub, so your feature request might be rejected if they go against those principles.

-Notification Email
-========
-
-GitBucket can send email notification to users if this feature is enabled by an administrator.
-
-The timing of the notification are as follows:
-
-##### at the issue registration (new issue, new pull request)
-When a record is saved into the ```ISSUE``` table, GitBucket does the notification.
-
-##### at the comment registration
-Among the records in the ```ISSUE_COMMENT``` table, them to be counted as a comment (i.e. the record ```ACTION``` column value is "comment" or "close_comment" or "reopen_comment") are saved, GitBucket does the notification.
-
-##### at the status update (close, reopen, merge)
-When the ```CLOSED``` column value is updated, GitBucket does the notification.
-
-Notified users are as follows:
-
-* individual repository's owner
-* collaborators
-* participants
-
-However, the person performing the operation is excluded from the notification.
