It is .clan(position) now? I tried it without "clan" and it worked in V8 I am sure. That or my memory is screwing with me again. As for the pic, that is how Laremere did that in his server. I wonder why he took .name out though.
I did:
findclientbyname("lare").clanprefix = "<bitmap:add-ons/system_returntoblockland/images/icons/cake>";
It may be cake_16, I forget. For some reason half of the images there randomly have _16 added to them, while the other half don't.
