I'm trying to do a test migration of my site to 6.2.5 and I would like to make some changes to the emails that are sent out for Notifications and private messages including:

1) Message Subject - Just want to do some minor tweaks.

2) Message Body - Specifically want to remove the actual message and add a link back to the PM system so that people actually come back to the site to read the message rather than just hitting "reply" which won't work.

3) From Address - I prefer to use a "noreply" address.

I assume that 1 and 2 are located somewhere in the resources files.   If this is the case, does anyone know the name of the keys that need to be modified?   Also, is there a list somewhere of tokens that can be used to change the templates.

Not sure if #3 is an option somewhere or not (if not, it should be)

Any help would be appreciated.

 Thanks
