There can be multiple wiki's on the same subject, there is no rule against that. Sometimes is can be more beneficial for several small wiki's to join forces and merge to form one bigger resource, but that is up to the respective communities.

You can look into Adoption for the wiki you've been working on. If you meet the requirements, you can file an adoption request in order to receive bureaucrat rights for that wiki.
