My intent in creating this post was to move much of the "Welcome" message into an "announcement" post that would be set to "display at top", so that it would always be available without overflowing the limited "Welcome" space provided by the new Google Groups interface. However, it seems that the new interface doesn't even have the "display at top" option! *sigh*.
In any case, this may yet be a useful posting, as it can be used to collect an expanded list of links to other TiddlyWiki resources.
Note: this probably shouldn't be used to publicize links to specific TiddlyWiki implementations (such as NoteSelf, Stroll, etc.). Instead, it should list sites that are hosting TiddlyWiki-related communities (i.e., "social media" sites) such as Twitter, Reddit, Discord, etc. and possibly also "index" sites such as "TiddlyWiki Toolmap" that provide lists of links to popular TiddlyWiki implementations.
To that end, I will periodically edit the top post to incorporate suggested sites so that this doesn't grow into a long thread of postings to sift through.
