...in a pixel art atelier?

I was thinking about creating a post where members could try Pixel Art, whether for improvement, learning or just fun.
A little like therapeutic groups that make you do activities, you know.
I could give 'exercises' to do and provide instructions/tips for anybody willing to try.
Then, I could make a gallery section where I would put all the pixel (attempts).
Quality will not matter at all, as everybody will be welcome to participate.

Oh, and also, anyone could share their experience and give tips to others too.

Was thinking about it for a while now, I thought it could be fun.

So I can rise an army of pixels and invade the forum mwahahhahha... Wait, did I write that down?

I just saw an account with a new 5 gen pictogram but on the account page, it's said that it has been registered/a member for 4 years.

Here is the account I'm talking about.

How is that possible? You cannot change the pictogram of an account that was registered way before the picto gen came out, right?

I would like to know and understand, because I don't really see the reason but...

What is the purpose of a Tumblr or Spotify for a character?

I have seen many people doing this, but I could not find the reason of why.
Can someone explain me, please?
