Yes, in its simplest for the master tiddler “transcludes” the other tiddlers, which imports [their] text field and displays it. <$transclude tiddler="tiddlername"/> but this can be done using list widgets.
- If there is a collection you then want to export as a group you can do so, for later import
- Further you could use a template to export a custom view of anything in tiddlywiki.
It does, it has public and private wikis and users and logins to your tiddler host account. This is limited compared to your original request, but it has basic one editor and multiple reader options. You can share the login but again one user can save over the others changes if not carful.
It is importiant to understand tiddlywiki can do almost anything, the only question is how much effort you need to put [into] it, to make it work. I have committed to using it as my key software tool, and thus know most of it. There are only a few places where it is difficult, but there is nearly always a work around.
- There is also always work underway such as Announcing the MultiWikiServer Plugin
