Meat Ball has a page on Twin Pages. And I created the twin here on Wards Wiki, because I can only afford to participate here.
I do find at times Twin Pages content on Meat Ball to have complementary value, and there are also instances of superior presentation and /or content there as well.
Do people here who have Meat Ball experience know what is a proper way to replicate material here that is sourced from Meat Ball? Please also provide advice on a way that can be tolerated (in case the proper way is too laborious).
I would like to copy something that is related to community communications, for example.
If it is your own material, you have the right to copy. But why copy it, when you can annotate it with a Trail Fire mark or by a Dii Go annotation. The annotation allows Wysi Wyg input and even embedding of video objects. -- Fridemar Pache
My suggestion for representing (handmade) bidirectionally connected (in- and external) Wiki pages is, using the pseudo-icon '<->' at the bottom of the page, followed by a list of all pages that are bilinked. If the pages have the same name, then I suggest the pseudo-icon '<=>'.
Pour information Meat Ball a aussi une page sur les Pages Jumelles en langue Française.

In my use of the Smallest Federated Wiki, I implement a system where alternate sites using the same tag may be noted concisely
here is the code for Twin Pages which is placed in a SFW:
Twin Pages<sup>c2 | mb </sup>
The above shows a link to the page in SFW, followed by two superscripts, one for the page on Wards Wiki (c2) and the other for the page on Meat Ball (mb)
It utilizes two to four character tokens for sites (meant for wikis, but intentionally used for any sites
For the tokens used in my personal convention, see:
