Thanks to everyone for their responses. which I appreciate. Not sure if everyone "gets" what I am trying to say though???
My point was that there are some posters on here, who are much younger. I entitled the post "14 ish". as granted there is no way to accurately pinpoint anyone's ability (regardless of age), and maybe I am being naive, but my intention was to help, not hinder, or to suggest that young people do not give valid advice and opinions. My post certainly does not come from frustration, I have all the patience in the world, if it means that I can help someone, regardless of their age.
There are other forums, where being marked as a "teen" is beneficial, as it allows young people to identify each other, and chat. I don't think it detracts from the advice they give. and personally, I have been given very good advice by young people, especially as I am a relative newcomer to Fishkeeping. but that aside there are many teens on here and elsewhere who are very advanced in the hobby and are able to advise regardless of the level of expertise.
