Well, that is not really a LeftBar question but OK; You did not specify how the system is to differentiate if it is you or visitor that is connecting but here's a simple way:
I'd use my TW-Admin plugin <http://tw-admin.tiddlyspot.com/> (with the sample content provided) to hide the sidebar and it's toggle arrow. Maybe that is enough? For you to access it right away, you can have a bookmark to the tiddler $:/plugins/TWaddle/tw-admin/content so you can toggle back the sidebar. If you use different domains for your TW, maybe my PublicSidebar <http://publicsidebar.tiddlyspot.com/> is of interest. This shows different (right-) sidebars depending on url, .e.g if you do your admin locally and then publish for readers. <:-) -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
