Recently there has been suspicion of the upcoming patch having the potential to block all forms of alteration to SC2's MPQ archives. It's not yet 100% confirmed, but we can't take a risk of ignoring it until it's too late. For more information, read here; http://www.teamliquid.net/forum/viewmessage.php?topic_id=355575

MPQ modding causes no harm to SC2 and opens a lot of potential for the community to develop and share their creativity to the players. With current mods shared to the TeamLiquid.net community such as Stronger Team Colours by Pzea469, proven to be beneficial to players affected by colour-blindness, and various other mods like Custom Backgrounds developed by Existor and myself, Teliko, we've brought nothing but a better playing experience to the community and opened a whole new aspect of entertainment and creativity to the game.

It's clear a change like this wouldn't affect negative aspects to the game such as maphacking, so there's really no reason to shut this down. Many players continue playing the game simply on the basis of knowing they can freely make it look however they want.

If you support mods like Stronger Team Colours, Custom Backgrounds and Dark Protoss/Mercenaries, and want to see more releases and development to continue after the patch, please sign this petition.
