How to post to the xkb list?

[cheater00 .]

Hi guys,
I have tried sending a message to the xkb list by sending a new email
to xkb at listserv.bet.ru. Google responded saying "We're writing to let
you know that the group you tried to contact (xkb) may not exist, or
you may not have permission to post messages to the group."

I have gone to the web interface for the group:
https://groups.google.com/a/listserv.bat.ru/forum/#!forum/xkb

That tells me I'm a member but I don't see a place to post a message
or to reply to existing ones. Does the admin perhaps need to enable my
posting status manually?

Thanks
