I created an issue for the task of archiving our slack history to apache - if you have comments or suggestions please have a look here to comment or reply to this email.
In essence: exporting the history from Slack yields folders for each channel and files for each day of communication for that channel. At the very least we can serialize the export and send an email per day per channel to a specific Apache mailing list. subject: [channel name] [day] where the content is: [timestamp] [user id|name] message https://github.com/apache/incubator-openwhisk/issues/4272 -r
