A website and application
allowing one to include graphical (as opposed to the usual plain-text) emoticons
in communications (especially e-mail). Doing so requires first installing the application. The catch is, to see the icons, receivers of the communications must install it, also. In this way, use of the program spreads by peer pressure.
Many consider smileycentral malware
, since it installs several other programs, and pops up advertising.
Many people find smileycentral icons totally annoying.
