Let me know if this format is OK, or whether there is a more helpful way I can lay out the information.
Overlay -> Friends: The text says "Add them using the Add friend link above", but the link is actually below the text.
Overlay -> Achievements: "THROUGH YOUR HARDWORK (...)" should read "THROUGH YOUR HARD WORK (...)".
Overlay -> Achievements: The Custom/Skirmish game achievements are inconsistent, reading "PLAYED 10 CUSTOM/SKIRMISH GAMES" vs. "PARTICIPATED IN 50 CUSTOM/SKIRMISH GAMES" and "REACHED 100 CUSTOM/SKIRMISH GAMES PLAYED". I don't know whether this is deliberate.
Overlay -> Achievements: Either the first or the second word in "REACHED PLAYED 100 SKIRMISH GAMES PLAYED" should be removed..
Overlay -> Achievements -> Build a City: "CITIES PROVIDE SHELTER AND A MEASURE OF SAFETY TO THE SURVIVORS OF THE CATACLYSM" should end with a full stop.
Hiergamenon -> Game Concepts-> Cities: "(...) city, including its yield, income, research and production breakdowns click its medallion (...)" should read "city, including its yield, income, research and production breakdowns, click its medallion (...)".
Hiergamenon -> Game Concepts-> City Details: "Each city has a maximum population designated by that the food in that city" should read "Each city has a maximum population determined bythe food in that city".

Hiergamenon -> Game Concepts-> Armies: "You can see how many units are in your army (...)" should read "You can see how many units there are in your army (...)".
Hiergamenon -> Game Concepts-> Pioneers: The written text is completely different from the voiceover text. If keeping the written text: "Placing the city near monster lairs will cause them the lair to be destroyed when your influence expands over it" should read "Placing the city near monster lairs will cause themto be destroyed when your influence expands over them". "Also, every city you place will have varied potential based on the yields of tile you settle on" should read ". "Also, every city you place will have varied potential based on the yields of the tile you settle on".

Hiergamenon -> Game Concepts-> Quests: "(...) a quest location, note that while trained units cannot start a quest they usually can still assist in their completion" should read "(...) a quest location; note that while trained units cannot start quests, they usually can still assist in their completion".

"Also beware of enemy units that are in the middle of casting" should read "Also be aware of enemy units that are in the middle of casting" since the meaning of the following sentence is that being in the middle of casting means you should try to stop them, not that it makes them particularly scary.
