Contributors and other members of the Volunteer Squad can add or change Database Items or add images. If interested get in touch (using the green Contact button here on the right-hand side).
Others (or for duplicated entries)
All registered users can flag Database Items. You will find the Flag button on the bottom of each page -
Please give us as much information as you can about why you are flagging an item. Flags will get reviewed by a member of the Volunteer Squad. At the moment there is no feedback loop but we are working on a page in the Curation Dashboard where you will be able to see your flags and what happened.
