@davimacedo I refactored the teams page, not only was it completely outdated but the layout was confusing.

We are using the img tags now, because it seems that the original GH image URL does not respect resizing for profile pictures that are auto-generated avatars. So if you add a new member, you can just replace the /u/xxxx/ in the img tag for the new member UID instead of replacing the whole img URL.

Let me now if you need access granted to make commits on this branch.

I am actually not sure whether we should keep the Alumni section; maybe in the past where there hasn't been much community care and less fluctuation in members it made sense. But as we are aiming to grow the community now we will have more fluctuation and create just a long list of users with likely little value to the reader. It may also be unfair to contributors who did not become team members and therefore won't show up on such a list.

Sure, I've sent an invite.

@mtrezza I've just completed the team section. Could you please take a look?

@davimacedo I have simplified this a lot, so we stop spending resources on keeping this team page updated and can finally merge this PR.

• Removed alumni
• Removed contributor list, there is a GH page for this; doesn't have to be updated manually, especially as we expect this to become more dynamic
