Would it be possible to answer issues and comments directly by replying to the notification e-mail? (GitHub supports that.)
If so, would it be possible to disable the "edit" feature on a per-repo basis, so that notification e-mails don't become outdated?
Indeed, editable comments force the person reading the e-mail notification to go check upstream if the content of the message hasn't changed since then.
this is a feature request for upstream gogs
notabug tried to stay as close to the upstream as possible; so this feature would probably not be implemented on notabug - if you would like to see this feature in notabug, the thing to do is search for any open issues on the gogs issue tracker relating to this feature and poke them to implement it or open a new one if thnone exists yet and ask them to implement it
any feature that is added to gogs will end up in notabug on the next routine upgrade unless there are freedom or privacy issues
