i need help with a global db change

[Preech]

I want to update my membertable with my sites reopening date as the join date for all my members. So basically the site has been closed for 3 months and i deleted all the old posts....i just want to update that so that all the old memberlists carried over have the reopening date as the join date, 4000 members would be a little much to do by hand

i run vb3.0 by the way if that makes any diff with the command structure

please help
