So i've been wondering what this option at the top is when you complete something like send a message to a user you haven't messaged before or something, what will you get? For what is this

Free coupons for premium packages usually.

This was done last year as well, but I assume you weren't around then.

i was but haven't seen it, maybe i wasn't online

yes that's interesting. but i don't find forums with easter eggs in them

There currently aren't any to find! You may try the global challenges though. I'm not sure if you'll succeed with the only one that's there now though, because more users already completed that challenge than there are easter eggs for it.

@hozosch is that easter egg thing also translated in german in your elten client?

I now have a notification that 2 Easter eggs are awaiting being found, but there are no further challenges.

one of them in polish forum!

Yes, it is.

I just created an audio post in my blog, does it need to be commented or why isn't it counting?

Ah, now it is.

Yeah, it just takes awhile, like it did last year.
