Hi, I'm wanting to make it so when a moderator goes to the frontend User Approval/Rejection page, they can add a note that is added to the welcome email. You already have it there as a rejection message that goes out saying "rejected for the following reason:".

How do I achieve this? 

Thanks, this is good to know, at least I can think of another way now, I'll try your suggestion.

Just as a FYI the reason for having or using the approval reason is to supply the new user with a payment amount without sending another email alongside the welcome email. this way the moderator can just add the price and hit approve. The site I am working on has pricing that changes depending on the time of year (each quarter has different pricing, as they send out invoices at the same time per year). I have suggested other methods, but they don't want to change their existing system  .I have looked in cbsubs and can't see a way to change pricing depending on the time of year (anyway this solution using csubs is mute for now as they want to keep it manual.).

Is there a way to insert the rejection note into an email and i can just change the wording on the Rejection note heading?
