Mike, So, non-technical users... - Finding phone numbers for a particular range of exchanges in a large document and changing the area code. - Reversing all names of a transcript (e.g. lines start with <first> <last>: "quote" and become <last>, <first>: "quote"). - Finding every instance of an email address *not* followed by a particular domain name. - Changing every date reference in a particular format to a different format (e.g. MM/dd/yy to yyyy.MM.dd) without affecting other numerical references (e.g. scores like 93/100, or 6/10). Those could be needed by anyone, not just IT or Tech Services. HTH.
