Hi,
at http://wiki.openstreetmap.org/wiki/Talk:Wiki#Forming_a_Wiki_Team I asked the senior wiki users if they would like to build up a group of experienced users that help others on wiki edit problems.
To make right, this is for support only and not to do the edit work for others.
IMHO for newbies this would be a good way to remove barriers for the very first edits, especially on big pages.
To the wiki this is hopefully another step to make it more lively and to coordinate the works of the seniors (e.g. Cleanup drive).
So what does you say? Good idea?
