Re: Welcome Pack update request
No, it doesn’t let you change any of the standard emails that a WPMU or BP site generates.
The next change I am going to make is to get a site “message” sent to new users on registration. Whilst I too need to be able to customise the emails, I’m not sure if that functionality is going to go in Welcome Pack or not. I am thinking the WPMU & BP emails need to be addressed either as patches to their respective software, or as a separate plugin that is in no way BP-specific.
This assumes, of course, that there isn’t an existing plugin out there that will do this. I haven’t searched.
