You wanting to know if resellers are caught up in the leak? Pulse8 told me no, only direct customers are effected and only basic info (assume address and tel no) are given to TT during the ordering process so they can migrate you.
Indeed I do have a reply in My Xilo but no email, does the ticket not send an email?
That is what happened to me and I do have email set up for tickets. I know it works as the first couple of posts in the tickets DID result in emails to me.
