I think this is a great idea, but please add more detail for a site proposal. See guidance here: https://meta.codidact.com/help/proposals

You could add information here. Even, you can answer on those question why you want this sites. Why you are interested. And, what you will do for those community.

@Sigma Thanks for support. I don't got other text to add, because the linked Proposals explain and justify the importance of these subjects so clearly! But you can edit my post to add text if you want! I'm just desperate for these subjects to get their own website here. That's why I made this post.

@Istiak See my comment ^^^ to Sigma.

If the people who want each of these overlaps significantly, then combining them won't significantly increase the amount of support. On the other hand, if they don't overlap significantly, then it doesn't make sense to combine them into one community.
