Pre-Fill Forms From Last Use

When deciding which form fields to pre-fill in, take into consideration that cookies larger than 4k might not be accepted by the visitor's browser. (To see how much that is, create a plain text file and add to or delete from it until the file size is 4k.)
(The plain text version of this article is a bit over 6k in size.)
4k is more than you're likely to need if you're keeping track of only a few items of information, such as name and email -- even if you have dozens of forms and each form has different field names for the same information.
If you're keeping track of many form fields, especially if some of those fields are text areas that invite lots of information, keep the 4k limit in mind.
