Greetings OSM folks;

I wonder if you could assist.

Students are still getting locked out and are unable to complete their
assignment. Also, the message they are receiving see below states that you
were unable to locate me, which we know is not the case.

It would be really great if we let the students finish their assignment and
that we discuss what to do with the messy data as discussed in earlier
parts of this stream.

Any assistance would be most appreciated.

"Dear COMS2200A students,

welcome to OSM and we're happy to see you engaging with our shared database.

A few of our community members have taken exception to some of the things
that you mapped and how you mapped them; many of your edits are not exactly
following the quality standards we have set for us in OSM which leads us to
believe that you may not have received the requisite training, especially
where you've made edits outside of the university district.

Sadly we couldn't find out who the person responsible for this
class/course/ activity is. A few mappers have commented on edits that you
made, and pointed out errors or problems; this should have triggered
e-mails to the address used when registering but the messages seem to have
been ignored.

Could you please inform your teacher/course leader to get in touch with the
Canadian community on the talk-ca mailing list (
lists.openstreetmap.org/listinfo/talk-ca) so that we can discuss how to
continue this exercise without degrading OSM's data quality?

Please pause your editing activity until the matter is cleared up.
Thank you Frederik Ramm OSMF Data Working Group
