We now have the option to attach prefixes to thread titles - for example, this one has the prefix Query. Does anyone have any recommendations for terms they would like to use as prefixes for the Citadel?

So far, I have come up with:

Hint
Query
Strategy
Research

Have I missed out any obvious ones? Prefixes should be short - one word or abbreviation.

A lof of the other obvious ones - technical, MP, modding, AAR - are not appropriate for the Citadel as we have other forums for them.
