I just read back, Nibbs, and you should be fine. It's giving out personal banking information to collectors that's the bad thing. You don't want those guys having control over your bank account in any way. But since this is the company you seem to have used for a while to make your monthly payments to, it's no big deal I don't think.
But yeah, I'm a big fan of automatic bills pay. We don't have debt payments, but I can't even imagine paying the payments we do have with checks all the time. I mean, I guess I did when I first graduated college, but with the mortgage and utilities, etc. I'd totally miss one on accident!
