@agjohnson
Need your advice here.
Also, I think we should store the date on which the user is notified for requesting a namespace to track the 6 week period.
And I think the code in this PR is little in-efficient in terms of speed and memory. Can there be any improvements?

[agjohnson]

Great, this is looking good so far! I didn't do a full review, we'll hopefully get to full review of this shortly, but there might be a delay in review here as this is off our roadmap.

I gave a really quick glance and this seems to be replicating our notification system. You should move the email/on site notifications to use this system instead of using django pieces directly.

@agjohnson
Thanks.
Also, I have a little confusion, I think the notification system built is for the users who are logged in.
But the message This project is abandoned is to be shown to everyone on the project page (readthedocs.org/projects/project-slug/). So, I don't think that we can use that here.

I didn't do a full review of this, but tried to give some feedback regarding the notification system and an issue about changing the slug directly.

[dojutsu-user]

I closed and reopend the PR for the travis to restart.

Still valid bot.

[humitos]

It seems that this PR is getting stale over and over again because we haven't had the time to review it. @rtfd/core we should try to take it a look or close it for now if we feel that it's too much outside of our roadmap at this point.
