copyright transfer contract update

[Romain Lenglet]

Hi, 
I signed my copyright assignment contract to contribute to Autoconf back in 
2006, and since then I have moved to another employer, and I'd like to 
contribute to Automake as well. So I'd like to update my copyright assignment 
for Autoconf and extend it to Automake.
Shall I contact assign at gnu.org directly, or has the procedure changed?
Best regards,
