I also wonder if there is a way to keep the site info and pics in some electronic format besides a database on a server? As far a maintaining a server goes, there is quite a bit of difference in maintaining static read-only site and one open to posting and new members.
Yes you can save pages as pure html and read them offline on any browser without the need of a server (you loose all the forum functionalities except reading and moving between pages).
There are also software known as website downloader or website copier that let you do that.
Pa is Very large tough and the process of an entire copy could take Alot of time and end up in many GBs of disk space
It can also slow down the site as the server would be requested thousands of pages (as many as a man manually visiting every single forum page)
Usually download softwares provide features like partial download based on filters but in my opinion they are not suited for our case.
