Title says most of it. I find these ones the most helpful for chat and for helping all users. The url's are pretty self-explanatory of what they will link you to. If you have any that you want added that I don't have, comment below and I'll be sure to take a look! (Thanks to clou44 for some of these links!)

tinyurl.com/eccresapp
(Resident Application)

tinyurl.com/eccscreenshots
(Wiki page on how to upload screenshots)

tinyurl.com/eccapps
(Link to the General Application's page)

tinyurl.com/ecctradesign
(Wiki article on how to create a trade sign; Edited by yours truly :p)

ECC website's with short URL's:

ecocitycraft.com/donate
(Leads to the General Donation info page)

ecoctiycraft.com/vote
(Voting page :D)

Additionally, here is a general tip to help all of you guys that don't wanna go to tinyurl to get one website down. There is a simple way to make all of your ECC threads clickable in chat:
Lets say we want to go to this website:
http://ecocitycraft.com/forum/threa...cookie-sold-to-sick24-for-125k-revised.61860/
Obviously, this is too long to post in game in the chat. To make it available to click the full link in chat, edit the url down to this:
http://ecocitycraft.com/forum/threads/61860/
Here are the revisions I did:

Hope this helps guys :)
