I do a fair bit of tubmailing. My frustrations include:

Not being able to type names in the from field.

Not being able to send a message to multiple people.

Not having “mailing lists”

I figure there is a good reason we can’t do these things. I think I could cobble together a Java application that would do these things, but that seems to go against ET’s implicit hacking policy. Same goes for Greasemonkey scripts, which I don’t know much about anyhow.
