Предложение по форуму (ну или я совсем ослеп)

Уважаемая администрация, сделайте тег "спойлер" или покажите где он есть :(
Очень часто (в жизни и пару раз на этом форуме) хочется использовать сиё изобретение, что бы просто спрятать "многобукаф" от тех, кому это не надо или неинтересно

ROT13 ("rotate by 13 places", sometimes hyphenated ROT-13) is a simple letter substitution cipher that replaces a letter with the letter 13 letters after it in the alphabet. ROT13 is an example of the Caesar cipher, developed in ancient Rome.

In the basic Latin alphabet, ROT13 is its own inverse; that is, to undo ROT13, the same algorithm is applied, so the same action can be used for encoding and decoding. The algorithm provides no cryptographic security, and is often cited as a canonical example of weak encryption.

ROT13 is used in online forums as a means of hiding spoilers, punchlines, puzzle solutions, and offensive materials from the casual glance. ROT13 has been described as the "Usenet equivalent of a magazine printing the answer to a quiz upside down". ROT13 has inspired a variety of letter and word games on-line, and is frequently mentioned in newsgroup conversations.

Можно еще Base64 или
UUencode использовать.

Русфаодиннадцатьен, на "что бы" можно было спрятать целый пробел для экономии.
