Ann: Non-Renounceable Rights Issue Offer Document, page-5

jason, you will be entitled to 1 new share for every 2 you hold, if you have them at the close of trade on thursday, they go "ex" on friday morning..........that is your right, and, you can, if you wish, apply for extra, usally folk apply using Bpay, and all you have to do is decide how much you want to stump up, and just apply, no return of forms etc..............
if you want to speed things up, you can go to the Advanced Share Registry site, and download your acceptance forms, but i think, Advanced dont do that, in which case they can email it to you. If your mail service is ok, then no need to bother...........
an afterthought...........expect the share price to fall, "ex" rights, sometimes back, close to the raise price..........not always, but worth watching
