This is more of a licencing issue than a code question. I really like the ckeditor editor and would like to use it in my freelance projects which I do for clients. However upon reading the license page it has me in a bit of a confusion. DO I have to buy licences if I intend to use this in cms websites that I build myself and hand over to clients?
If so then what are my alternate options which don't cost anything?
Its should be ok, if you don't change anything of its source, IMHO.
