Changing the account with which I am chair of two CGs

Hi Ian,

My company (Ponder Source) became a W3C member last week, so my username
changed from https://beta.w3.org/users/49046/ to
https://beta.w3.org/users/143305/
Can you maybe add my new username as chair of
https://beta.w3.org/groups/cg/unhosted/ and
https://beta.w3.org/groups/cg/timesh/ , or let me know how I can do this
myself, if possible?
I think I was only able to add the new username as a participant in both.

After that I will delete the old account and I can continue to be chair of
both with my new account. :)

Many thanks!
Michiel.
