I fully support you and your crosshair making, You know why? Because anyone who says "Crosshairs aren't add-ons" and "they take up space for something so small/useless" and whatnot, It's just ignorant, Really it is. If someone popular on the forums like pandan or whoever posts something like.... a Custom Handgun made from scratch, Are you going to troll him for post ONE thing and using a new forum post? Didn't think so, Yet if someone you don't know posts 10 or 5 or however many crosshairs or ui edits, you'd explode on them like they're really doing something wrong. Now while you go around trying to "Moderate" (Not quoting anyone specifically), Don't bother, That's Badspot and epialtes' job's. Trust me they're pretty on top of things, So if crosshairs and ui edit's weren't add-ons, They would've been gone a LONG time ago, And they would have had their own sections. Now if anyone wants to argue with me what an "Add-on" is, Do it, I have a definition and a site.
http://www.techterms.com/definition/addonAn 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.
What's a crosshair do, Replaces the one you already have, Thus adding something to the game's interface. Now people would argue "It's not ADDING, it's changing, well yes and no, although it may be altering the interface, the crosshair still needs to be put into the game, thus the adding, It's more of a subtract & add.
