 Please do **not** use this issue tracker as a discussion forum. Discussion related to the bug in question should of course go to the issue itself. However other discussion should take place at the [community forum](https://whispersystems.discoursehosting.net). You can use that forum to discuss any Signal related topics or to just hang out with your fellow users.
 
 ### Don't bump issues
-Every time someone comments on an issue, GitHub sends email to [everyone who is watching](https://github.com/WhisperSystems/Signal-Android/watchers) the repository (currently around 500 people). Thus bumping issues with :+1:s, _me toos_ or asking for updates just generate unnecessary email notifications. Moreover bumping an issue does not help solving it. Please be respectful to everyone's time and try to only comment when you have relevant new information to add.

 #### If it's open it's tracked
-Have you followed all the points in the [Submitting useful bug reports guide](https://github.com/WhisperSystems/Signal-Android/wiki/Submitting-useful-bug-reports) but nobody has commented on your issue? Is there no milestone or person assigned to it? Don't worry, the developers read every issue and if it's open it means it's tracked and taken into account. It might just take time as other issues have higher priorities. And remember that this is an open source project: Anyone is encouraged to take an active role in fixing open issues.
