So I understand that I can open access to wikis by turning them public. But I wanted to figure out how to give some other logged in users the permission to add and or edit tiddlers in a wiki. For context, I have a friend whose learning 3d modelling with blender and I wanna get started with 2d digital art and I wanna set up a shared wiki so we can share what we learn and what we made in an organized way. (Don’t worry about file size, we’ll be using a shared drive and share links to that instead of putting it on the wiki)
It might be safer for your remain solo editor of the TiddlyWiki, and have content that is multi-editor kept on Google Drive (Docs, Sheets, Slides, Drawings), because those support simultaneous/collaborative editing really well.
Say you have a TiddlyWiki tiddler about Blender. Create a related Google Doc (where everybody can put in information about blender, and add comments related to whatever) and embed it in your tiddler.
Now your TiddlyWiki has content that makes sense there, but also acts as a portal to content that maybe makes more sense somewhere else (for simultaneous/collaborative editing and/or whatever else?
That doesn’t fit the kind of flow I’m trying to generate, but I appreciate the suggestion. Do you know any other way to have an online hosted wiki with two contributors? Any leads on where to look for something like this?
Please please please make a decent TiddlyWiki APP that people can use solo or collaborartively
It’s a tragedy that such a great tool is so difficult to use in a browse
The elephant of TW is you just save your work and share easily.
Heartbreaking really 
TiddlyWiki running on nodejs on a Google Compute Engine virtual machine (or any other place that will host a TiddlyWiki on nodejs for you.)
Not necessarily options for the faint at heart.
I still think shared Google Docs/Sheets/Slides/Drawings as extensions to your TiddlyWiki could easily fit your workflows. If you ever want to give that a spin and test out, I can give you tips/pointers/etc.
Pretty sure setting up true collaborative capability isn’t a trivial affair.
Pretty sure it is something that would make single-file TiddlyWiki quite heavy and slow.
For collaborative capability with TiddlyWiki, TiddlyWiki on nodejs hosted on some server is pretty good.
