I recently discovered SendPage() using the Byond Reference, however I didn't see anything on there to check if the key inputted, AKA the recipient, was a real key.

Is there anything I can use to check if it's an actual Byond Key?
Using Topic() and world.Export() you can get info from the text-field-key to check if it exists.

Two more procs I have no knowledge about that I need to look into.

Thanks for telling me I'll check it out!
No problem ^^
