Permit moderation of employee posted topics

As an employee migrating topics into GS, or otherwise adding new topics to GS, I'd like the ability to modify the description of the topic (not just the title) because I may have made a mistake and there's no easy way to fix it.

Note that removing a topic is an option, but currently the reasons for a removing a topic do not include "user error/mistake". The work around for us now is to create a new topic, merge and/or bury the old topic. Just seems unnecessarily complicated when we just want to either edit the topic or remove it.
