Hello Richard,

I apologize if my words sounded harsh or offending. I admit that I'm not
regular user of Potlach, so my knowledge of it is kind of limited. But I
can see the mistakes other users do and well, guess, what was the
underlying reason for them.

I came across basically two categories of relation bugs caused by users
using Potlach.
1) Pointless members of relations, e.g. a German train station added to
the Czech administrative boundary relation. My guess is that the user
mistyped the relation id when he/she wanted to add that station to some
route relation. I have no idea, why he/she did not use the method,
you've described, but it happens.
2) Generally broken relations, e.g. the user deleted a way that was part
of large forest polygon, probably because the way itself had no tags. I
presume this is caused by not very good visualization of relations in
Potlach, thus most of the time users are simply unaware that they are
breaking something. A simple task like seeing that the way/node is part
of some relation requires a user to switch to Advanced mode and look at
the list. If he wants to see the extent of the relation it's another two
clicks away (menu for relation>select all members). If he wants to see
what that relation is or edit it, its double-click away (from the
Advanced mode).

Please, don't take this the wrong way, I value the work you and others
are doing on Potlach. I'm just pointing out a few flaws, that I spotted.

Best regards,
Petr Morávek
