They get it with their move-in folder in the little biz card slot.

it was happening to me last week. almost every time i'd click on "post reply", it would take me to a "server error" type page. when i go back and post, it would appear twice.i had a thread about it too.

Most most landlords when the rent is late do not first serve some kind of a notice with a process server.

Here is in Illinois, it is strongly recommended by most attorneys to use a server to serve any notices including 5 day notice. 

I use the storage room at my apartment building installed a very nice mail slot and gave the door a number.

Notice the singed neutral slot (the wider one).

Legal notices can sometimes be delivered by Process Servers (private entities) instead of the Sheriff or other law enforcement. 

I have 4 loan slots filled (including this one property).Looking forward to your insights!

Unfortunately, I won't be able to provide much help if you are on another email server.

All of that to say, the primary gaps in my team are the contractor/subcontractor slots.
