Hi,
currently we have template “Lokale Gruppe” that is germany only to represant a user group even on a map www.openstreetmap.de
In agreement with the author Jochen Topf we now will replace it with a more general template:
http://wiki.openstreetmap.org/wiki/Template:User_group
We hope that we will be able to make a map of all groups on a central place. This might improve the teamwork in our world wide project.
Any hints and suggestions are welcome 
Do you think that [[Template:Lokale Gruppe]] would be best moved to [[DE:Template:Lokale Gruppe]]? An alternative would be to prepare a German version of the [[Template:User group]] and put it into the DE language space. (I’m not that familiar with how the language spaces work, but thought I would put in my thought anyway)
hi the bot is now online http://wiki.openstreetmap.org/wiki/User:UserGroupsBot
Jochen agreed that when it runs on a public system we will migrate to the new template.
