I'm no expert, but it seems like the template for this forum is pretty standard and wouldn't require the effort required to fit calling it "not practical." As for level of interest and participation... Have you stopped by the Fishing Reports subforum lately?Sure, but you won't like my take on it. Honestly - I wouldn't hold my breath waiting on this one. It's not practical to add a subforum for every possible topic, it just doesn't make sense. So, they way we've always done it is if you have an idea for one you start a thread in here to gauge the interest and if gets enough interest then it may get considered. This thread has been here for 4+ months and while it's gotten 50 something posts, there's only been maybe 9 or 10 people actually expressing any interest. That's not exactly a huge interest level.
Now all that being said, it's ultimately OS's decision as he's the only one that can add a forum. But like I said, I wouldn't count on it.
Now, I know it's not yours or any mods decision. Just pointing it out is all. I mean, we have a cooking and recipes subforum, but a financial and economics subforum is not practical...?
