I prefer the way leafnode2 works now: post only once for moderated
groups, but repeat until successful for unmoderated groups.
One suggestion --- if you think it's practical: when building the
groupinfo list, if leafnode gets different flags for the same group
from different upstream servers, I'd like 'm' to have priority over
'y'. (AIUI from previous discussions, the local flag for a group is
more or less randomly picked from the upstream flags.)

Is that hard-coded in the source code somewhere?
