Newly created accounts cannot make large edits or add hyperlinks. This is to combat spam and vandalism. If you're trying to make a large edit and encountering this problem, make a series of smaller edits, saving in-between, until you are no longer considered a new user. It's a good idea to save large changes to a text file on your computer, so your work isn't lost in case of problems.
