Stumbling trying to understand this great plugin. I have a twist to using it to invite people to review a profile/users page. No issue just modified the header and footer to give an appropriate message and just the link to the profile. The attachments option is tantalizing, I don't see much documentation on how it can be used. What I want is to attach a file which is already in the user as the field CB-Myfile which was previously uploaded using CB File Field. I thought I could just add the [cbimyfile] example but it does not seem to work, in fact anything I add does not seem to add an attachment.
Does anybody know how this bit works and if it supports files from the user sending the invite?
