I think that they have removed links to it as I have had to include some advertising to help pay costs - nothing devious just a couple of links and even they appear in the fiendishly named "shop" so that anyone who wishes to avoid such blatant commercialism can simply not go into the said "shop".
It all seems a little hypocritical, as TSR themselves have ads by google (which I dont) and a very flashy rotating banner on all pages (which I dont)
Still, who are we to wonder why...
If anyone has any IB chemistry related problems they can still google "IB chemistry" and they will find the site at no. 1 (and 2) - during the run up to the exams I also provide a live helpline for anyone really in stuck.
Thanks for your support Mauve.
