Pay attention to the contributions of others. In addition to motivating every participant, you’ll enrich each other through these exchanges.
Your contribution only make sense if others appreciate them. Hence, address the remarks… they’re meant to help you give the best of yourself.
Everyone can make his/hers contribution, may it be correcting a comma or to helping configure a forum… Everything counts!
Contributing should also be seen as a mean to learn new things, for ex: learning the lojban, telling stories, use the wikis, etc.
