^^^ 1999/09/13 shows hate and air portal spells being changed to a higher level spell. Which lends me to believe they were open at this point.
Patch notes 1 month later show ro opening.
So, Hate was in on live before temple of ro was.
patch notes 1 month after that showing levitation is no longer gonna work in poAir.
^^^^ hopes this clears things up
