Hi John, I really like this, but I think your "source:maxspeed=AU:urban" below is a typo. It would be simply
maxspeed=AU:urban Does anyone else have thoughts on this? Could this be our default (site-unseen) for residential streets - or is this an across-the-board solution and we combine it with a source:maxspeed tag of some form to determine whether site-unseen or surveyed. John - as for the Wiki, I agree with you, a lot of Aussie stuff needs to be in the Wiki, and following global standards if they exist. A lot of useful stuff gets discussed in here, but I believe the bulk of contributors do not subscribe to talk-au. They probably don't know or care about list. They use JOSM / Potlatch presets as an editing guide - failing that, they fall back on the Wiki and the Help Centre for clarification. I see a useful role for talk-au to be a melting pot for ideas and local policies that should be disseminated via the Australian sections of the Wiki.... but, who has the time and motivation to take on this task is another matter!!!
