Using Invisible Ink
In our wildest spy fantasies, in addition to the any number of ruses employed by undercover agents, is the use of invisible ink to communicate covert messages in plain sight of the enemy. But while our part in the drama may be fantasy, the use of invisible ink &ndash in a variety of forms &ndash is very real; its uses ranging from the commonplace to the extraordinary.

Invisible ink is used within the confines of any ordinary writing device. The message is written on ordinary paper; once the ink dries it is no longer visible to the naked eye. The method used to make the message visible again depends on the type of invisible ink used at the start. These methods fall into several generally accepted varieties:

The method that most people associate with invisible ink is that which is developed under the use of ultraviolet light. This can often be seen in the way of hand stamps used for readmission to amusement parks, night clubs, and the like. What is not visible to the naked eye suddenly glows under a UV light.

Free Essays on Invisible Man: Invisibility
Invisibility is usually taken to the extreme effect of truly being transparent, unseen by anyone and is often depicted in society as the hero, going behind the enemy?s back to complete his mission. In Ralph Ellison?s The Invisible Man this view of invisibility is turned around so that a man is in plain sight of everyone but do to a lack of observation nobody recognizes what he accomplishes. After beginning the novel as a man who stays quietly out of the way by doing what he is told, he is forced to leave and mold his ?power? into another use.

Our nameless hero takes us on a journey that extends both concepts of an invisible pacifist and aggressor.

What Is Freelance Seo Writing?
SEO writing is one of the newer forms of freelance writing spawned by the Internet Age, and as such, SEO writing is an excellent way — if at times a frustrating way — for budding writers to cut their teeth in the freelance writing scene. SEO writing takes a fair amount of imagination and some engineering grit, but if you like puzzles, then freelancing as an SEO writer will interest you.

SEO, or “Search Engine Optimization,” has its roots in the early days of the Internet. Once early Internet marketers realized they could manipulate search engine rankings with meaningless content and keywords, a whirlwind of keyword-stuffed web pages swept across the Internet, all designed to push their content — and the products they sold — to the top of search engine lists. This sharply increased user traffic and potential profits. It wasn’t uncommon to see web pages with only a few short paragraphs of copy with large, seemingly-blank areas of space. However, if you highlighted these blank areas of space with a cursor, it would reveal massive strings of invisible keywords. SEO writers used to embed invisible keywords in text to rank the webpage higher in search engines for nearly any remotely-relevant search term.
