I'm sure you can find a post someplace to make a interesting comment on.
You could give a good job to someone's report, maybe put out a thought on some form of fishing.
What I'm saying is be productive or fade away
I disagree that users who don't comment on posts aren't productive. Not every post needs hundreds of replies. Plenty of people respond on forum to what they want to respond to and when they want to respond. If registered users want to just read posts, fine with me, at least they're a registered user and can interact how they want on this forum. Some registered users like to respond to anything and everything posted, and that's fine too. It's just a fishing forum and everyone has different ideas and expectations on how they want to spend their time on here.
