While not important in this case, it's really not possible to delete posts
from Usenet. You might have removed the post form Google's servers, but
even if Google sends cancel messages to the newsservers they peer with,
some servers do not honour cancel messages. And in any case, the post has
already been downloaded by many clients.

Speaking of which, an error message popped up on GG when I tried to
reply to another post of yours (incidentally it was the same message I
saw before I doubled posted last time): 'An error was encountered
while trying to post, please try again later.'

For some reason some of my posts are now taking hours to show up on GG
as well.
