I have been watching the fine efforts in greater LA, with impressive
progress and results (in a "slow and steady" way), so I first wanted
to congratulate you on your efforts, and especially reaching out to
this talk group. You have done much more than scratch the surface,
you (and others) are making real progress.
One method may be to revert changesets by blars. Reverting
changesets can be controversial (it is polite to ask / reach
consensus with the original author, et cetera). However, in the case
of an editor who has not agreed to the new CT, it may be correct for
OSM users who HAVE agreed to the new CT to establish if/when/how this
is an OK/proper thing to do. And then feel OK doing it, and then do
Technically, reverting a changeset is rather easily done with a JOSM
plug-in, which you can read about on OSM's wiki. There is the
separate issue of IDENTIFYING which changeset to revert, which can be
"more difficult" and then there is the rather straightforward
procedure for doing it, which isn't difficult.
But "socially," or more properly stated, in the context of "reaching
OSM consensus," what does our community think of (rather wholesale)
reverts of a contributor who has not agreed to the CT? Are we OK
with that? Apologies if this is already clearly stated somewhere.
But if so, I haven't seen it and it is high time we freshen up
how/where we are about this.
