Caps?

No they aren't. Unless there's an old one that you haven't gotten. I did randomly get one a few weeks ago but it was pretty much a fluke. Other than that I haven't seen a cap in years.

And you can still get medals but earning them is a little weird. No one has really figured out how that works; I've contribute to the music club regularly and have done so for years but still only have the yellow medal. I contribute a lot to certain clubs and don't have a medal at all but have received one for a club that I haven't even looked at in years.
So yeah, you can still earn medals but who knows which one you'll be getting lol.

Only those from X years on Fanpop membership. If you're under 6 years here you might still get one of those caps.

Holiday, special caps, no but they still give out writer caps, showing love caps, expert caps, etc but that's about it. Medals are really hard to get, you just have to be patient and contribute as much as you can and wait. And wait...
Hope this helps :)
