CK Editor feedback

Can I get some feedback on those of you who have used CK editor for your websites? I have a chance to manage a site that was originally built with using this but I have no experience on the implementation of setting this up and using it to maintain and update a site.

Thanks,
Brian

I don't have any idea regrading with the same too. I am just a newbie for that, however, I just browse on the internet to have a research to be able to have a knowledge on that and it works. All you need is just a thorough reading ad understanding. 8-)
