Hey Galaxy Girl. from what I gather, they are yet to advise of a venue. On my invitation the venue was also TBA. I have accepted and assume that as the date approaches I will hear of the venue via email or phone. Another suggestion is just reply to the email they sent you..im sure they wouldnt mind at all if you were worried and wanted to just make sure you havent missed anything? Actually, let me check and see if I still have the ph of the recruitment officer and if so I will PM it to you. Either way im sure it will all work out!
Goodluck
Cheers
