There is no such thing as a Project Administraotr of this Wiki. This Wiki is the place for comprehensive discussion of the Open Source Geospatial Foundation. Check out the http://www.osgeo.org site for stable information and individual projects and their respective Project Administrators, Committee Members, Chairs, Sofas and such. This Wiki is only administered not managed and not moderated. To keep it this way a WikiSysop is needed to make backups, maintain the software, etc. That is Benjamin. The backup Sysop is Arnulf. From a technical perspective they do everything to the system. They do not edit any content that way though. Whenever they tinker with content they do it the same way as everybody else, cerate an account and hit the edit button and leave their traces in the history.
Yet this might change. Because it might happen that non-benevolent users or machines spam our Wiki. These polluters are by nature evil, folks also call them spam robots. Whenever a spam robot spills informational waste the WikiSysops comes into action and exerts pollution control. These methods include IP blocks, page protections, etc. Whenever you feel that the Wiki is being polluted please immediately report to Arnulf or Benjamin.
Rest assured that "pollution" does not translate into "stupid" or "wrong". Whenever you think someone edited something stupid, or wrong - go hack it yourself and do not bother the administrators with it. They will only react to repeated mechanical spamming and direct order from the president ([User:Warmerda Frank Warmerdam]). If somebody appears to put stupid comments in the Wiki it might be a Troll. Trolls are very important for the health of a Wiki community although sometimes they can get really on your nerves because they mess up everything. Well, they are Trolls. Nonetheless in a healthy ecosystem you need all kinds to make a world, be it informational, environmental or technical.
In some larger Wikis administrator privileges have been misused to change content or prevent people from changing content. Both are incorrect use of this authorization and must be avenged, usually by revoking these privileges. If you think that a WikiSysop has done soomething like this please immediately report to Arnulf or Benjamin. In the best case report directly to the WikiSysop herself because it might be that she did not mean to break anything. In the worst case report to all the user lists that you know. Rest assured that avenging is going to take place.
