Thanks for looking into this. Sounds like you guys are approaching this right.

If you have to do changeset rollback, there are scripts for it. 



You have to be very careful. I'm not sure if this is something we want to 
introduce to COSMHA yet or not, as it takes some programming skills. The trick 
comes if these end up being "dirty reverts", where objects have been editing 
after these changesets.

I've done this before, and could volunteer to do it, if needed. I would need a 
list of changesets to revert. We may have to iterate on that, in case of dirty

Dear Jean-Guilhem,
(Nicolas, Mikel, Robert, Kate: if you have tips on undeleting in
general / in the Haiti context pls do share them.)

Excuse me for answering only in English but I it seems that you
understand English well (and hope that Google Translate does a decent
enough job for those who don't). I'll try to use my (crappy) French
when I have better time...

Thanks for bringing this to the attention of others (as well as making
note on the tertiary issue, which I'll comment separately).

I don't know this new user who has done the deletions but I will ask
at our next mapping "party" (or perhaps rather an "OSM meetup") at the
Grass Roots United resource center (http://j.mp/osm-gru) next
(upcoming) Friday afternoon (5/27).
... As a sidenote, if you are (or anyone else who is) in Haiti: From
now on we'll have weekly OSM meetups / mapping parties (?) at the GRU
resource center starting at noon that are (obviously) open to anyone
and everyone interested in OSM/mapping Haiti. (I'll make a separate
announcement with the approriate subject).

I'm copying this note to a few people who are / have been active here
and know more about fixing deletions that I do hoping that they could
perhaps share some knowledge about how to tackle the deletions.
Quite frankly, I'm a near newbie when it comes to undeleting /
reverting changes and I'd really want to get help on that so I don't
mess up more than I may already have in the undeletionings I've

* I'll ask if someone knows this new mapper
(http://www.openstreetmap.org/user/Josep3) and can contact him via
other means
* If no one else fixes the deletions before we'll look at this at out
meetup/mapping party.
- Hopefully we'll get some more experienced help to the undeleting or
at least re-inforcement to how to do it.
