Just a little reminder, political debate is probably the mostly highly protected speech that there is. It's arguably the reason for the First Amendment.
While I realize that you can moderate your own forum, I wonder that you should set a particular set of rules in hopes of limiting discussion of a controversial political candidate. This seems contrary to what you, as *journalists* should want.
I'm sure each of you, as journalists, has had off-the-record sources. There are often good reasons for not using one's name. Many of us, for example, do not want our children penalized by this debate, but still want to be able to bring up important issues.
Particularly if there's an election at stake.
