Help:My text is tinted

If you paste in text from a word processing program and it ends up tinted / with a grey background, it's likely that the paragraphs are starting with spaces.

Example:

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer cursus sem nibh, sed porttitor augue congue nec. 
Integer finibus sed felis a cursus. Sed lacinia, odio in euismod accumsan, risus risus mollis urna, eget aliquet orci lectus eu purus. Nunc nec faucibus nisl.

Simply remove the leading spaces and it should stop being formatted this way:

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer cursus sem nibh, sed porttitor augue congue nec. Integer finibus sed felis a cursus. Sed lacinia, odio in euismod accumsan, risus risus mollis urna, eget aliquet orci lectus eu purus. Nunc nec faucibus nisl.

Starting a paragraph or line with a space is called "preformatted text". Note it does preserve single line breaks, which are normally ignored by media wiki — usually to get a line to break, you have to have two returns in a row.
