Links will forever remain broken, it's an unwritten law of the Wikis and it will forever remain that way. Trust me back in my days of KSP wiki editing, I learned this the hard way. Links tend to break themselves if you even dare look at them funny...
Other then that, The wiki defiently has improved since it's really early days. Nice to see an actual Wiki dedicated actually to the... rather dead Clanning Community. (Seriously somebody needs to move the corpse, it's attracting flies and making the whole house smell funny)
However my only criticism is that you should present Clans without a Pro-Union bias, I've noticed a lot of that used heavily on the VT, RSR, and Operation Lunar Shitstorm pages. I get this is the Union wiki so everything relies on a Primarily Union perspective, but doing it in a way that is neutral and unbiased helps give a more clearer picture of what the clan was, what it did, and what we can learn from it. Especially in the case of some of the larger Clans like RSR, REA, FR, and Vacteee Pewp.
