I fixed the box header name issue (apparently there are TWO places that it needed to be updated)

Still couldn't get the javascript to show up in the sidebox, though.

As a work-around I put the newsletter sign-up script into a sidebox2 bannerbox and that seems to work fine.

I would still be interested in learning what I did wrong with the editable-sidebox mod since it seems like a very valuable mod and I would like to be able to use it.

Have a great weekend!
