Tiddlyspot.com has closed its free services for hosting Tiddlywiki and there are alot of Tiddlywiki files on Tiddlyspot.com which cannot be edited / maintained anymore.
Fortunately Tiddlywiki is enough flexible to be able to switch to alternatives very quickly. Here, there are two alternatives
GitHub Pages
This is the recommended method, it needs like one hour, to set up your new account on
https://github.com/ and host your Tiddlywiki using GitHub Pages. You can build a whole website using this method. It is possible to maintain the page as a collaborative work (but needs a little more efforts)
1. Tiddlywiki older than TW 5.1.20
read carefully the instruction tiddler.
2. Tiddlywiki based on release 5.1.20 and newer [recommended]
This method is simpler, straight forward and better for non-tech people.
The published Tiddlywiki on GitHub can be accessed by any viewer has the site URL and a rather new browser!
Google Drive [The simplest - Limited to Android Users ]
Tiddloid (
https://github.com/donmor/Tiddloid) and TiddloidLite (
https://github.com/donmor/TiddloidLite) are two freely distributed Android Apps can be installed on an Android device (phone/tablet) It can simply create a Tiddlywiki (or any number of wiki you like) on Google Drive the same way you create a new one on your local disk. You can open your wiki using Tiddloid and edit it and save back to Drive.
The Tiddloid works simply and any non-tech user can host his/her Tiddlywiki on Google Drive.
1. If your audiences have Tiddloid you can give access to them from Google Drive
2. If you want to share to anyone who has not Tiddloid you can share it but viewer has to download and then open the Tiddlywiki, the browser does not open directly Tiddlywiki from Google Drive
NOTE:
The hosted Tiddlywiki on Google Drive can be accessed by any other viewer has the site url . You need to distribute the link to viewers (See Share Files from Google Drive)
