This is an attempt to make a list of things that someone-group of people can follow to develop a healthy community or team. This post is an overview of what I did with Kostas for the Greek openSUSE community.
A small detail is that we were only 2. So we took decisions fast. We didn't have to vote or something.
We had an "advantage" because we have an awesome global community and we asked for something we weren't sure how to proceed.
0. Have a clear goal. What you want to do. Have a big goal that some parts aren't "visible" when you start.
1. Web page: This is the web page-blog that will show information about community, the distro or the project. Make it visible on planets. BE CAREFUL. Don't focus on how to make a great site-blog using personal wordpress, drupal etc. Set it up on blogger and start post articles. You want CONTENT (write an article every other day). Don't spend time to maintain or secure your web page.
2. Mailing list: Ask the project if they can setup for you. If not, then try to find alternatives such as google groups.
3. IRC Channel
4. Forum: Prefer to ask from the project to setup a section for your language. If your project doesn't have forum, then ask a LUG or tech forum to use their's. Do not have your forum setup in your host for the same reasons as before. Don't spend time to maintain or secure the forum.
The above list is the MUST have to start.
A key to everything is to try to have all information in your language, so it'll be "attractive" to people who like the idea of open source but they don't speak English. What's the role of such people? They can organize local events.
Next step is to advertise the whole project-distro. This can happen:
1. Write to blogs-forums (technological or not).
2. Create Facebook group/page and advertise your attempt to other groups/pages.
3. Create Twitter account and tweet news about your community.
4. Create Google Plus Profile/Community.
5. Contact press. First contact local and then national press.
6. If you have a newsletter or weekly magazine, it's good to translate it (or a piece of it), so the open source community in your country will learn about you and your projects.
Before deciding what social media accounts to create, be aware that you have to maintain them. So search the web, what social media is more famous to users. For "tech" users, Google Plus Communities is the perfect place. It also can be used instead of Forums.
A distro or project, it's not all about write code. It's have fun. So advertise it.
1. Release parties. When a new release is out, it's time to party.
2. Meet ups. A good place to organize them is http://meetup.com/. A meet up can be also a hangout.
3. Special teams. Check Fedora's example.
4. Beer-drinks. Check out ChicagoLUG.
5. Organize events on your own (start small and then go big). For example install fest or special nights (2 hours of projects presentations and 3-4 hours hacking). Join events (even cohost with other organizations) or conferences that will show people what you do. You should search some big events in your country and attend. Here is a tutorial about your presence at conference.
6. Then go big. Examples? Organize something like openSUSE summer collaboration camp or if there's a global conference, you can host it.
After you find people to follow you, then you can let them run special tasks (such as social media handling or forum moderator). When you're all set locally, then you can go global and show what you did.
During the process, don't act as leader or president. Since we're all volunteers on this, no one likes if someone is ordering people to do tasks. People like coordination. Someone that will remind the community deadlines, news, special days. Announce the results of a task, cheer up people by reward them (somehow).
People don't follow you for what you do. They follow you for why you do it.
So you have to know why you create a community.
A very good reference is Jos Poortvliet's blog about 5 steps to organizing a meetup. It's a small start that might go big.
