Why is this challenge with a different small art icon? 

Thank you so much Adarias

Thanks SoloSalsero, the news item was tagged incorrectly causing it to not appear in the feature page.  I have fixed it.

THe challenge this week is Tiny Monsters.  The warning sign challenge was "manually closed" due to having zero entries after 7 days.  The manual nature of this transition is the source of the subsequent hiccups.

In addition, the way to find this discussion is from the main page and scroll down to find the topic (Pixel Art Challenge: Tiny Monsters), but if I enter from the navigation menu Features > Challengues (Weekly!) the discussion doesn't appear

I'm confused, what is the challenge this week (March 29, 2019)?

Ofc, you can do as many as you want.

Does have to be only 1 or can I do more? max 24x24 each of course

I was actually planning on creating something :O

As a matter of fact there are sometimes challenges I want to do - the problem is that I either forget or lose motivation, or I give up midways because I'm no pixel master and I already have so many participation ribbons :')

i see. next time i'll do one on sunday and have 7 more days for the other two.

btw, if you guys wonder why there's not much traffic on the challenge thread: it maybe is because the link is missing 

If we had even 1 entry it would mean that, but as of last week's result (no entries, no comments, no forum posts - while the rest of the site traffic was quite busy) it felt like we wouldn't get 3 entries even if we waited for a month. You see, it wasn't a popular topic.

So I started a challenge where one can make an entry in under 1 minute and still no entries on wednesday. This time I'll make 3 entries on sunday if we don't get any

Summary: If I create challenges every week, I get stressed and fail.

oh. new challenge. so no entries means that the challenge will not be extended for another week?

fair enough, i'll save the danger-signs for the clean-your-harddisk-challenge then :)
