Hello!

I've prepared tiny patch to fix picksplit function in the cube contrib
module and sent it to hackers mailing list in monday. It wasn't posted
to mailing list. I sent my letter another time, but result is the
same: my letter is still not posted to mailing list. I added patch to
commitfest, but now link to the patch is broken. I have questions:
1) Do we have some troubles with mailing list moderation? May be
moderator have a vacation now?
2) What is condition to have possibility to post to mailing list
without moderation?

With best regards,
Alexander Korotkov.
