Please register your productive opsi locations

[d.oertel]

Hello,

we ask all opsi users which use opsi productive (!) to register their location at
http://www.opsi.org/map/

The registration is free and causes no duties.
These map is a important tool to document progress and spatial distribution of opsi.
It helps also to get more paying customers, which are needed for maintenance and development of opsi.
