If you want an icon of your guild added to the game, please do the following:
1) Create a 16×16 PNG icon. The background must be transparent.
2) Send it to email@example.com with subject “Guild icon – GUILD_NAME – GUILD_LEADER”
If your icon looks okay and is 16×16 transparent bg, we will add it to the game.
Please be aware that decision of what icon is okay is taken by game administration and is not a subject to discussion. If it looks bad, has some religious/politics/social signs etc, it’s definitely not okay. It also should be in harmony with guild name.
