Unfortunately there are a few on here that will take the time to answer with a non-answer like “this has been asked and answered in the past” which is discouraging to new shooters. I like reading the opinions of new posters. Sometimes you learn something new. Not everything has been answered in the past.
This will be unfortunate for my first post on this forum but here it goes... I agree. I'm a member on many other forums for other interests - motorcycles, engines, jeeps, cars, hunting, fishing, electronics, etc... The same issue exists. "use the search button" is a common response. If that is all I have to say, I generally don't reply. I could just as easily tell someone to go read a "muzzleloading 101" book.
I do get the frustration of having to rehash the same information over and over, but a forum was never meant to be a searchable database. The good thing is one can usually find 100s of threads on a topic. That is also the bad thing. Often they are inconclusive, or very old, or don't specifically address everything you want to know. I do usually search, extensively, mainly so I can formulate a better question when I do post.
A forum is created to have a place for new conversations. Many things could have changed from a post that occurred 5 years ago, or new members might have fresh ideas or perspectives to offer. I say, participate if you want to, or don't... no harm in letting those that are willing to chat do it.
If an experienced guy took a new shooter to the range to teach him how to use and care for his rifle, I doubt he would say "you should have searched the forum before you came here" when he asks simple questions.
