Allow a role to edit a specific taxonomy list of terms We have a blog that needs to be categorized by topics. I want to allow a blog administrator to add/edit/delete blog topics that are listed in a taxonomy vocabulary. But I don't want to give him add/edit/delete access to other taxonomy lists. Is there a permission that I am missing? Is there a D7 module that handles this? Or can someone point me in the right direction for writing my old module?
Taxonomy Access Control provides this functionality.  Workbench does as well, though it is slightly more complex and from my limited experience performs better when only a single term is used per node to control access.  Workbench (access + moderation) includes a nice set of tools for content moderation and workflow not found in Taxonomy Access Control. Both are worth a look before you decide for your use case.
