So why am I waffling on about taking classes and learning new things? Well as we all know communities grow and evolve all the time. New members join, old members leave, the dynamics of the membership change and the site matures and adapts. So all this change means that as a community manager I need to grow with the needs of the community. To be ready for change, to anticipate the needs of the members and to act accordingly
When you've been with your community a long time, and watched it grow in size, its very easy to get stuck in your ways. The "if it's not broken, don't fix it" mentality is hard to break free from, especially if you are afraid that rocking the boat will result in something falling out. But if we don't learn new ways of doing things then the communities that are entrusted into our care will not flourish.
If you don't want to stretch your brain muscles in a classroom then instead learn from other community managers. Find out what works for them, what doesn't. Ask questions of others. Participate in communities for Online Community Managers, read some blogs, read some books. The most important thing is not where, or from whom we learn, but rather that we are open to new ideas and suggestions so that we can grow along with the communities we manage.
