One of the best things about using Codeigniter is obviously the community and how easy it is to find solutions to your problems. You have a lot of options, the IRC channel, the forums, the awesome documentation and you had the wiki.
Well codeigniter moved all the code from bitbucket to github and that was awesome. However, ElisLab always had their own wiki. People used it a lot, adding libraries, helpers and some good advices on how to do stuff with the framework. The sky was the limit and there was no disturbance in the force.
