If I want to have a url in a file with ":set spell" I have to either mark the link as correct or deal with the red hilighting. Is there any way to white-list everything that starts with "http://"? Thanks in advance.

> Great. Thanks for the response. I am relativity new to Vim though, so I have no idea how I would go about setting up syntax hilighting rules. The closest thing that I could find in the help file was something about "contains=@NoSpell" but I do not really understand it. How would I go about setting it up, or at least, where could I read more about it?

> You can type this directly, put it in a mapping or command, or put this in a file with pretty much any name you want, in ~/.vim/syntax, and set the syntax to the chosen name to activate it. E.g. if you name the file ~/.vim/txtspell.vim you can do :set syntax=txtspell to apply the rule.

> Well, I thank you, Ben Fritz. I stuck that line in my .vimrc file and it fixed my problem for the most part. I still do not understand all of the syntax behind it yet but I should be able to figure the rest out with the help of the manual. It has been a pleasure learning from you.
