I always liked Opera besides some of irritating behaviours which are by design. The login failure only happens (at least only here that i know) on Rog Forums whereas notebookreview's forums work just fine with Opera.
I don't know why it fails, maybe login variables are sent incorrectly or the forum package (vBulletin) behaves differently with different mods when compared standart vBulltetin releases, in this case, Rog edition.
Well, sticking with FF right know. Just wanted to know. Thanks all.
