Y'all know there are forums for older, more mature people right? Like millions of 40+ year olds posting and not a twentysomething in sight.
You're never to old to write messages to other people, what sense does that make? Communicating with text is an essential part of life for billions of people.
You'll probably stop posting here with the young idiots, but it would make no sense for any of us to stop posting when we get older. Think about it, if anything, forums will improve in the future and we'll ascend to more sophisticated forums.

That will never stop being part of many, many people's lives. It won't be shameful to post in your 30s and up, it might be shameful if you're posting with teens, though.
You are a poster who enjoys socializing and expressing themselves with text, and you most likely will be for the rest of your life.
