ok... will everyone SHUT UP about Crosshair's and UI edits, You all say "The default one is best"... Well that's your own personal opinion, nobody has to do ANYTHING that you do or what you want, some people like to get crosshair's and UI edits, sometimes certain crosshairs really DO help people, and some crosshairs are fun just to play around with, if you don't want them, then don't take them, nobody is forcing you to do it. And i mean, if crosshairs REALLY weren't add-ons, don't you think that the forum moderators would have removed them by now? But no, in case you didn't notice, Every crosshair and UI edit put onto the forums has remained there to this very day. And if I must i will give the TRUE definition of "Add-On"
Add-on: An add-on is a software extension that adds extra features to a program. It may extend certain functions within the program,
add new items to the program's interface, or give the program additional capabilities. For example, Mozilla Firefox, a popular Web browser, supports add-ons such as the Google toolbar, ad blockers, and Web developer tools. Some computer games support add-ons that provide extra maps, new characters, or give the player game-editing capabilities.
