How close is version 3 to being released? Please excuse my ignorance, but I only found this software last week.
I would not expect the message to be translated, but shouldn't the mailer convert the static content to the receivers preferred language?
I forgot to ask, do you want an SQL dump, or a ikonboard backup? I'm guessing the dump.
If I can't find anything by this method I could create a board and try to fill in enough info to give you. My fear here is that I won't create a complete enough example to help.
