Back in the day there were quite a few knowledgeable folks on the forum that would post pertinent information, only to be told by the newbie/first catch/ member they didn't know what they were talking about.
But newbies can PM others with 'expert' advice (not suggesting you're a newbie, just suggesting that a PM doesn't necessarily mean the advice is gold).
What I like about open forums is that if you hang around long enough, you build up a knowledge base and get to know who you can trust and what advice makes sense.
Sometimes there are just different ways of doing things. I like to read about how different trappers do the same thing differently. It allows me to develop a bigger picture of the idea which allows me to think of ways that I could make it work for me, better.
I don't post here much because my lack of experience is embarrassing compared with some of you, but I used to post quite a bit on another forum where I had more expertise. I found that when sideways advice came up, the best thing to do was to call them out on it--the experience trappers know the difference between the good, the bad and the ugly, and the newbies learn to read between the lines.
Where differences of opinion came up, it was best to simply respect the other's opinion and leave it at that.
