Good to see that the links have been updatd for the various era pages, but there was one other timeline-related note I wanted to make.
The current timeline on the Jihad era page only goes so far as 3076. It might be worth expanding it to 3080, to cover events highlighted in Jihad Hot Spots: Terra and Jihad: Final Reckoning.
(Although, some of those "tail-end" events, such as the glassing of Circinus, might technically count as Republic/Dark Age era events instead.)
Actually, the Dark Age timeline is currently a bit thin regarding the Republic Era, and currently skips a few of the events noted in Field Manual: 3085 and/or set to be featured in Historical: Wars of the Republic Era, such as the Republic's campaigns against the Capellans and the bordering former-League states, the Second Combine-Dominion War, and the Victoria War.
