The announce URL I'm given on the upload page doesn't include a port number or a passkey.  This is what I see:

I'm not sure if this is a bug or not, since passkeys are added for each user when they download a .torrent, but I wanted to make sure before I uploaded anything.

You can put anything for the announce url or even leave it blank because it will be added again on download for each user. The tracker works a little different to most other sites as your passkey is unique for every torrent.

Ah, I see. I'd noticed that the last 24 characters of the passkey were different for every torrent.  Let the uploading commence, then.

Thanks for the quick response!
