Can I get an 'M'?

After a delirious conversation about the spelling of "commingle," I was relieved to read this on a fellow blogger's site.

You say commingle. I say co-mingle.

Does it bother anyone else that commingle is spelled with two 'm's? Dictionary.com says that the prefix is 'com' meaning 'jointly, together, with.' So it must be right... but it still bothers me. But I digress, and regardless of how it's spelled, a trustee has a duty not to do it.
