I keep planning on making a from creator like you are talking about but I haven't gotten around to it yet. It is possible but it may be a significant amount of work to make a generic form creator. It is much simpler to just make each form as you need it.
And for the second part, if you don't care about security you can just add a tag or field that removes the edit button from tiddlers you don't want users to edit. Someone has a guide to adding css based on tags that explains how to do it. So the answer to both of your questions in that it is possible but I don't know if anyone has made the things to do it yet. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
