A good tip to remove duplicate nodes.

If you look at the Philippines, we have very few compared to other countries :)

We have a bit of a push on at the moment to eliminate duplicate nodes
- i.e. where there's erroneously two nodes in the exact same place,
which should be a single node so they're joined.

== Identifying duplicate nodes ==

Some of you will have seen Matt's map, which shows "dupes" and is
updated almost instantly:

I've just added a bunch of dupe-fixing features to Potlatch. So when
you've used Matt's map to identify some dupes, click 'Edit in
Potlatch' and sign in as per usual.

Now click the way with the dupes in. It should be pretty obvious which
ones they are. :)

== Fixing duplicate nodes ==

To fix an individual node, select it and press J (for "join"). This
will delete the duplicate nodes and replace them with this one.

To fix all the dupes in the current way, select the way and press J.

To see what the dupes are, you can use the Inspector (in the Advanced
menu, or press I).

== Other stuff ==

I've also added a feature to "unjoin" junctions. (I think JOSM users
call this "unglue"). This is, logically enough, shift-J.

And this really is the last major improvement to Potlatch 1.x before
2.0, except for one more thing that's coded but not announced yet. :)
