It is very hard for newcomers in WME to be able to contribute as much as they wanted due to the ranking system that doesn't allow to do much at first. It is very hard to get to at least level 3 which allows to alter some segments in the driving area and it is almost impossible without hunting for missing POIs or stuff like that. There aren't always many editors with higher ranks and sometimes they can get overwhelmed by the editing tasks and opened map problems.
There should be a better system in place that would allow newcomers to better contribute to the map.
The system could inherit from programming CVS meaning that anyone should be allowed to make a change no matter for instance the segment level. This change would be just a revision of that segment and would require someone to approve it (like a pull request). Only after approval it becomes permanent change. There are small contributions like changing a turn or connecting a new segment to an existing road that you cannot do as a newcomer.
By changing the system the work load would be balanced better and everyone will get better chances of getting to higher ranks and experience.
