Dear group member and chairs: I am afraid I cannot attend OGF 26, because I cannot find fundings to support my trips. Besides I am struggling for completion of my PhD - writing up. Based on these circumstances, I have made the hard decision to quit chairing this working group. Nevertheless, I would very like to contribute my efforts to UR working group as a member. Many thanks for everyone's contributions and supports to UR working group. It was my great time to work with you! king regards! X.
