i) i could only find one place to change the code inside the private template?

Sorry, that was an error in the documentation. It's calendar.php that requires the double replacement, not private.php

ii) one of the template changes required you to add the name=vbcode as the form had apparently not been named. Perhaps add this to instructions

Done

iii) the "enhanced mode" just gives me a javascript error

That's wierd... I can't reproduce that at all, and I've tested with IE5, IE5.5, NS4.6 and NS6.0... have you got a link to a page where I can see this happening?

iv) when i tried to reply to a private message i just get "array". I don't know if this is because of the the vb beta 3 upgrade or because of the hack or beacuse i could not find the second place to edit the tempalte.

Likewise, I can't reproduce that either. A link would help in the diagnosis.
