PM issue with replies. Help requested :)

[halkum]

Okay so I'm working on a forum and can't for the life of me figure out how to get the PM system to allow for simple replys.

Right now we have three buttons on pm's.
'Site', for the users website.
'Quote', to quote the entire pm in a reply.
'Forward', to forward the entire pm to another user.

But there is no simple 'reply'.

I'm not new to modifications of vB or other forums board systems, but I just can't locate where this would need to be changed. Is it hardcoded into vB this way?

All we want is a simple button for 'reply' that replys to the pm with the subject as 're: ' and nothing posted in the content box, so it's a clean message, in reply to the existing. No quoting nonsense.

Any help with this would be greatly apperchiated.
Thanks.
