Great plugin- I just bought the developer version and I'm really impressed by its features. I'm building a website with a user registration piece and multiple other registrations, and it would be very helpful if the invoice generated during User Registration automatically emailed to the registrant.
So, I took a look through freshbooks.php, and added the following to line 1122:
and the email invoice was sent just fine. Is there an issue with me doing this and/or is there a better to do this than hack the current code? I'd rather work withing what's currently built than develop against potential revisions, so any help here is appreciated!
