horse accounts cleanup

[Craig Falconer]

There are 37 accounts on horse, and 24 of them have not been used for 
over a year.

I'm intending on deleting the old accounts sometime next week - if you 
want to keep it please login.

Anyone who has forgotten their password please let me know too.

I'm also following up on users with specific firewall rules.
