Currently there's only one admin (Johannes Schindelin), it would be healthy to have more than one.
Use user talk pages
For example this one. This way wiki-specific issues can be discussed.
For more information see mediawiki's help.
Stop immediate blocking
Up to now, good faithed users have been blocked immediately, and permanently, without a warning. Instead of doing that, a policy like wikipedia's one should be followed:
- Revert the change
- Notify the user (through user talk pages)
- If the bad behavior continues, continue with the blocking
Alternatively temporary blocks can be issued.
Revisit old blocks
Some people might have been wrongly blocked. By changing the blocking policy the old blocks might not apply and warnings should be issued instead.
Allow users to see deleted pages
This would allow transparency into the action of the admins.
Create a patrol group
Users, can help to patrol for page vandalism, all that is needed is the creation of a patrol group.
This way the burden of admins is decreased.
Disallow user pages
The community has expressed certain discomfort on letting people have user pages. It might make sense to disallow, or even disable them to avoid future issues.
