Hi,
That is the goal of our beautiful interface when creating a new thread.
You can provide a link and ask to be private, so it won't be display in the forum but we (the moderation team) will be able to see it !
Anyway, you can use private message or the "contact-us" form.
Please provide a link to that thread so we will be able to find it easily in order to update the issue ticket linked to that thread.
Regards,

By the way, do not send me private message, use the "contact us" form instead.
