The test Wiki with only a few pages is currently approaching 50MB not counting the database. Adding any images or other files will make this grow. I imagine that the database will also quickly grow. Even if this test Wiki is not to be
the Wiki, it can let us to continue to set it up. I'll look into how possible it is to export the database. I suppose that even if things have to be copied over manually, it will already be in the Wiki format, so little to no editing would need to be done for a second copy and paste.
As far as copying the Free SCI stuff over, you can't do a straight copy and paste. Any line that begins with a space gets interpreted as code and a single line break will not be recognized as a line break. It does not recognize BB code. It uses its own code for formatting. Links are handled different. See the following for more.
http://www.mediawiki.org/wiki/Help:FormattingIt does accept some HTML tags, like
br and
pre. You can hit the edit tab on a page to see how I've started to enter the Free SCI docs. You can create a link before you create the page. The link will be red. If you click on a red link, you will be given a link to create that page. It probably makes more sense to do an intermediate copy and paste into a text editor where you have a search and replace function to speed up the reformatting. Let me know if you need any more help.
