Caps?

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

And wewe can still get medali but earning them is a little weird. No one has really figured out how that works; I've contribute to the muziki club regularly and have done so for years but still only have the yellow medal. I contribute a lot to certain klabu 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, wewe can still earn medali 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 wewe might still get one of those caps.

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