Yesterday I guided a beginner through the upload process, starting from the Swedish competition website wikilovesmonuments.se.
There seems to be no connection between the two paths 1) participate in the competition ("delta i tävlingen"), which leads to the upload form on Commons, and 2) find monuments on the Google map.
I had expected that the Google Map would have an "upload" link for each monument, but I couldn't find this.
In the upload wizard, there was suddenly a field for the monument ID, but no indication of where to find this ID. Luckily I knew where the lists are on Wikipedia, but the upload form had no link to these lists.
Are these two problems unique to the Swedish competition, or are they the same for all languages?
Minor issues: Why is Google Maps used, and not OpenStreetMap? In the upload wizard, the choice of license has a terrible wording in Swedish. Where can this be corrected? Is it part of the WLM competition, or the generic Commons upload wizard?
