I can see that if I create several posts with the same link, they are matched as such. The other posts are linked in the «cross published» section at the top (on lemmy-ui).

If a post is relevant to two different communities (example: a climate-dedicated community and a more general news commyunity), should I post it in each ?

If so, how to ease the process without having to separately copy / paste all parts of the post ?
