A quick post to give people a heads up that there seems to be a google groups problem affecting the portable-gis group, amongst others.

If you have signed up with a googlemail account (not gmail, or any other email account) then your messages may get bounced back with a permissions error.  This seems to be a general problem affecting many groups, so no doubt a fix is in progress, but just so you know, I’m not blocking anyone (hell, I can’t post to my own group at the moment!).
