A prefix, to me, is first nothing more than a substitute for a subforum.
Instead of [cats], I could write [Forum cats] before or after a thread title.
With the prefix, I can put a topic in one forum, whereas without it, I might need it in three forums, or use links.
The prefix opens up new possibilities for multidimensional connections.
For me, it’s not just a filtering tool but also a label that makes an immediate statement in the topic title (in lists or threads).
It says: "This is about [cats]!"
If my forum is about cats and dogs, but also includes veterinarians and pet stores, I might not just want to label it [vet] or [shop], but [vet for cats], [vet for dogs], [vet for dogs and cats].
I could solve this with these three prefixes.
But they become long. So, I’ve used [vet][cat][dog] instead.
I don’t know if I’d want to give up multiple prefixes; without them, I might choose topics like this:
[vet] - Vets in Paris for cats and dogs
[vet] - Vets in Paris (cat), (dog)
Hmm, honestly, I don’t want to give up multi-prefixes. And I don’t see why they shouldn’t be a core feature. You can’t say that Xenforo always sticks to "Keep it simple!"—there are some odd things, like navigation level 3, for example. And jumping between main tabs.
With tags, I, or soon will, be able to connect topics beautifully. I plan to enhance their use and value.
But as long as tags stay small under the headline, they won’t get the same attention that prefixes do.
All in all, I’m happy with my view and usage:
Tabs connect two or three topics that truly belong together. (2-3)
Tags connect topics that should be in a list; here, I also use longer words or multiple words. (<21)
Prefixes connect topics that belong in a list (or at a certain number, they’re moved to a subforum) but at the same time, they’re clearly visible labels! [Warning!] (2-3)
Lists are handmade to show a couple of threads (10-20)
As a final touch, you could use, I forgot the name, Siropu’s add-on to connect words in text with something else. But I never really liked the add-on. I think it was too complicated and tiring. But I haven’t come up with a concept yet on how to improve it.
There was also a function in the Wiki add-on (sorry, forgot the name), for which I had some custom coding to connect words with a Wiki entry. These slugs work like Siropu’s word linking—certain words need to automatically lead to an explanation, a Wiki entry, another topic, FAQ, or whatever.
What else can i say:
Prefixes show a list of topics in a subforum.
Tags, on the other hand, always land on a global tag list; it doesn’t matter what forum or what prefixes are used.
And yes, the search and filter options exist, but they mostly annoy me. That’s why I took AndyB’s idea and changed it for myself—I search for many things through quick search. And now that I’m thinking about it, I should consider whether I need a quick search for tags.
