Can't Build Capitol?

[Deantwo]

Might I suggest an edit to the wiki?  In particular, an added explanation in the "Building Your First City" page about the need for founding an empire through crafting a flag. I now see that the explanation is present in the "Starting as an Emperor" article but I managed to miss it in trying to skip ahead to city management.

Yeah, I'll add a note about it in the Nation Age part of the guide. Since you don't actually need to make a capitol until then.
