Re: The wiki now has a CRS page

Thank you Andrea. I think it would be great if you can add corrections or
improvements directly to the wiki, and I encourage other to do so as well.

In line with WG policy that was discussed earlier, in case of differences
in opinion it is preferable not to use the discussion page (tab) on the
wiki, but to use this e-mail list.

Regards,
Frans
