Many people are! Like everything in life, it might have gone through a rough patch but it is definitely picking up lately!
Of course! It's just I feel that people are active at completely different parts of the day. So say during the morning for you, you might make a post, and then you won't see a reply until much later, which would be the morning for someone else. Either way, there are a few parts of this forum that are more active than other parts.
I guess the timezone makes a huge difference, but the forum is relatively active. There are some active users that post every day.
