Thanks for answer, @CH_ASUS !
I have two accounts - one for ZenTalk forum, and other for Asus web site, product registration and support. Both accounts are registered with same e-mail, but are different (I don't know why). New ZenTalk uses ASUS account. I don't know how to merge two accounts in one, so I save all my posts, ratings and comments from old zentalk to new zentalk. Will it be possible in future?
