As you may know on SQL Server a varchar column can hold up to 8000 characters (each row can hold up to 8K, so it depends on the size of other columns), when you need to store more it is common to use the text or ntext datatypes.

Shaun Innman posted about a technique he call's Widon't, for dealing with the widow problem on the web.

The widow problem is when you have a single word on a line by itself, at the end of a headline or paragraph. In typesetting this word is called a widow.
