I was cleaning up my hard drive, and found a link which led to this old forum:

https://hawaiifive-o.proboards.com/

Does anyone remember anything about this site (this dates back many years)?

I actually have a login for this board (dating back to 2012) and it seems to work up to a point, but then it wants you to "verify" your account by entering your credit card information (with no charge, supposedly).

I don't think so...
