Been trying to remember how, and been trying to skim through documentation in te help pages, and so far been having no luck remembering how to fave a tag or tag type over just faving an image.

I don't think that's possible at the moment

You could subscribe to its RSS feed, this is the only way I know.

Hmm. Must be an admin thing then? I've seen some profiles with tag subscriptions, which is why I was wondering. Would like to subscribe to Ami~ and Dark Nek0gami amongst others, so I don't forget about new arts and the like.

Tag subscriptions are privileged+

Privileged+. more info on that here. You could still do with rss.

• Ami's RSS: https://e621.net/post/atom?tags=Ami

Dark Nek0gami's: https://e621.net/post/atom?tags=Dark_Nek0gami

It works on basically any tag.

Never used RSS, so that's arcane stuff to me. I'll look into it though, thanks!

Subscriptions should still do this in a way, try going to https://e621.net/tag_subscription and edit it, for priv+ the interesting thing is that you can click the subscription itself and it shows all posts that have at least one tag of the subscription, for you however you it would be empty.
The thing they do for you is that you can click the tags separately and then look if you see something new, so you don't have to remember the tags.

In addition to tag subscriptions, you can search ~dark_nek0gami ~ami and get all posts with those tags, as long as you don't hit your tag search limit.

It'd be under oonami, but yeah, I already do that. It's more of a concern for new stuff that comes out. I'm notoriously bad at not checking inboxes and checking for new content unless I get a little nudge of a notification somewhere. I've already set an RSS feed now though, by using the link so generously provided by Xch3l (and modified to Oonami) so I should be good. ^_^ Thanks again for all your help, everyone!
