Zefir and all chip buyers, please take note the way burnin is taking orders by your username and wallet (he abandon the message singing method...). These info are all out in the open so it poses risk for somebody to stole your chips (they paid for assembly with your chips buying info and have it ships to them...). I dunno how burnin will verify info with group buys organizer so you guys have to work it out to prevents against this...SebastianJu has the same concern afaik.
I know that's not really Zefir's responsibility, but could his chip addressing system be slightly modified so that we can also enter our personal shipping addresses there? (ie not just to what assembler we chose). If Burnin was then given access to that info it should be easy for him to then cross check that address is the same as entered on his site.
