Saving blank passwords

Can you create option to save blank passwords (when user has no password). It's annoying each time press enter and if you forget to press, then you have time-out.

Sorry for poor english.

Blank passwords do not make any sense.

I can't say to owner of ftp, to add account password, becouse of my ftp client.
Each account (each one with no password) means different shared dirs.
And each time then smartftp trys to reconnect to server, I have to press Enter.
