Unless I'm missing something, at the moment there is a single email template for the invitation that is sent when you Offer or Request a file from somebody. The default text is:
You have received access to a Serv-U File Share from $FullName. The link to transfer your file(s) will expire on $FileShareExpires.
$FileShareTokenURL
$FileShareComments

Which illustrates the problem - OK for sending but very confusing for someone you are requesting a file from. It's hard to come up with wording that meets both cases and after all one is usually using the File Sharing feature to communicate with people with limited technical skills (otherwise they'd be using an ftp client!). Either separate templates or some sort of token that allowed you to have different text in the different cases would be great.
Many thanks
