While forum participation is seasonal even for me, the Folding Trailers section has seen an overall drop in usage in the last year or two. We used to spill over into the second page of threads with new posts within a day. It was a little hard to keep up when I first joined years ago. Now, we get maybe 5 to 10 threads updated in a day during the summer height.
Not that I don't have questions but I more often take to fixing something and trying it out than so much research. I guess increased confidence can be a dangerous thing.
I've also taken to posting less about things I don't know directly or have read about sufficiently. So I guess my overall postings have dropped dramatically.
