May I have the honor to take this responsibility?
I have experience on implementing r7rs-small, and I mainly focus on practical use cases of Scheme in the past decade.
I'm the maintainer of GNU Artanis, and I have experiences on POSIX interaction with Scheme. Like file I/O and socket.
I'm trying to establish my business on Scheme, so I will be consistently concentrating on Scheme and RnRS.
However, I don't think I'm the best candidate of a chair, since I don't have such an experience and I'm not a native English speaker.
Anyway, I would like to cooperate with folks who are interested on E.
