Starting your first book
Help:Starting a new page or book is a good resource. If you need specific help with something, ask at WB:HELP.
Reporting vandalism
Report vandalism in progress on-wiki or in #wikibooks. Say !admin@enbooks in IRC to get attention. You can fix most vandalism yourself because this is a wiki. Users who fight vandalism may ask for rollback access.
Why did you delete that?
Check the deletion log for the reason (read any linked pages for details). Read the deletion policy. Check the VFD archives if applicable. If that doesn't answer your question, then ask. If you want it undeleted, ask at WB:VFU.
What does {{query}} mean?
This means that the page doesn't seem like the start of a textbook. Please leave a comment on the module's talk page if you are planning a textbook. If not, please replace {{query}} with {{delete|reason for deletion}}.
What do {{no license}} {{bad fairuse}} or {{no rationale}} mean?
All files uploaded to Wikibooks must have a license template and source; without that information, the upload will be deleted after 7 days. Please use {{information}} to provide this required information. Fair use images must have a {{fair use rationale}}. To add templates, do not re-upload the image. You must edit the image description page directly, the same way you do for other pages - click the edit this page tab. Wikibooks:Media has all the information you should need.

I've retired, so there's probably no need to do that.
