Is it worth setting up 3.7.0?

[Judge Ruckus]

So I have been out of the loop for years. I am still able to access/DL vB 3.7.0 via vb.com. What I would like to ask is it even worth setting up on a site. I have no plan on creating a large community at this time but does that even matter?

By the looks of the mod section for 3.7 it does not look like many people are still using it. I am sure it is better to upgrade but that is not much of an option at this time.

Thank you to any and all who reply to this topic.
