I dont believe we have a wiki, although a lot of the older posts have been saved by SWGemu and several other sites easily found by googling what you need.
The most useful website is galaxy harvester if you plan to craft, I don't remember if it was out with live.
To my knowledge the developers are working on getting the ground game done before moving to space but the code for that should be easy.
The warreen, DWB, Fort tusken, jabba/nyms/rebel/imp theme parks are all in as well as George caves.
The only end game content not in right now is coreillian corvette.
The patch notes should be available below in the other fourm topic devoted to updates or patch notes the name escapes me.
If you need any help getting started you are more than welcome to email or send me a tell in game. I am an armorsmith and we have a good guild WS that makes great speed starter weapons and higher end weapons as well! I am located out of Halycon Tatoline and am part of CHC we are a Rebel/neutral guild if you are interested
You'll find most people on the server are more than welcome to help aid others
