As has been mentioned, the greatest number of visitors (so far) to the forums was just after VV2 came out.

So far as I can remember, most of the posts were along the lines of:

1. WOW! WHAT A GREAT GAME!
2. How do I ...?
3. When can I download it from [insert favourite games site here]?
4. When will it be available for the Mac?

Although the forums were apparently less busy when PT came out, the same sort of posts were made.
