Maybe also archive the reddit page on the wayback machine and add the link to the post? So in the event that you needed the original you could still view it without giving traffic to reddit.
Yeah. Sounds like a good idea for a browser add on.
It places a button by the post's title.
Click that and it asks you to click the relevant replies.
It prompts for any additional tags (autotags RDX and subreddit name)
When you're done it fills in the title, body, tags of a new Lemmy thread and sends the archive request to whatever service they set.
Yup, but this is to prevent me from getting lazy and putting off creating the post until "later". (Where later = never) It also reduced things like tag typos and incomplete entries.
