Tinderbox is administratively down because of some design flaws. We are working on new solution.
The new solution involves using BuildBot and a new bbclass for stats.
Using oestats for your builds.
For your builder to send reports to our QA server, you need to edit your build/conf/local.conf to make use of the oestats-client.bbclass class.
INHERIT += "oestats-client" OESTATS_SERVER = "tinderbox.openembedded.org" OESTATS_BUILDER = "your_nickname"
