This is probably a dumb question and a pipe dream, but is there (or can there be) an alternate way to logon?

I can access the site from work, but they have blocked the actual login URL. I dont know exactly what the URL is since I can obviously log on from home, but I know it has the word login.

Any workaround outside of having our proxy people unblock it? (I already asked them nicely but apparently it's a much bigger process..)

Thanks
