one of my usernames has a @ in it so this breaks the --servers :@: bit :-(
Yeah btcmine in particular requires the @. May need some sort of regex instead of .split('@').
I'm using the latest version with --servers at btcmine with the @ symbol and I haven't had a problem with it at all, all 4 miners
have been running for days with out a hiccup, So I don't think there's a problem with the @ symbol.
