I just tried to attach vcard to personal message to another forum member, so he can contact another person we are speaking of, and for which I have no invite link at the moment - but I can’t. Forum engine says :
Sorry, the file you are trying to upload is not authorized (authorized extensions: jpg, jpeg, png, gif, ico, toml, txt, mp4, xdc).
This may be an intentional (anti-spam measure ?), or just the default setting. If this is intentional, all I ask is someone to confirm it.
