I've relented and used Potlatch from work (forgive me on both accounts) to add some familiar street names around Moorooka (Brisbane, (sigh) Australia).

Seems a pretty straightforward interface, though I'm confused by my changes not showing anywhere except when I select the ways and look at the properties/tags from within Potlatch. Maybe I'm not saving them?

Have been saving tracks from the months or two, but not yet sure what use I'll be able to make of them.

Though this is addictive, I plan to try harder to use an open editing platform in future.
