Dedicating your website to your community is a powerful way to unite and help your community! You may dedicate your website to your town, church, fraternity, guild, etc and upload news and resources to the use of all community members. Such a website will certainly help your community get closer together, and unite around common problems and events.
Through your website, you may also popularize your community! You may post interesting facts about its activities and achievements to let the people learn about you . For example, if there is a unique natural phenomenon near your town, why not tell people about it? Such information may attract lots of tourists, make your town popular, and improve the lifestyle of your community.
