As I left BTTR in early 2005 and started working on www.4sceners.de
(as mentioned in an older thread here), I can't be of any help here. I don't know what's up with the site. Probably Warlock (from Warlock's ADF Archive), the server admin, knows more.
I'm still around in the Amiga emu scene and Cody Jarrett or Codetapper can confirm this. I'm just more active in the "background" today, but visiting and reading EAB and other sites related to Amiga emulation frequently.
