🙂 @Samsonroyal Are you already working on this?

Hello @RonnieLutalo I’ve been on it but would sure use some help 😁 are you available?

[ronnielutaro]

@Samsonroyal Yes actually, and I was of a view/thought that this issue's output should depend on a new issue I just opened. You may look/read through it and see how relevant that could be, make any suggestions where necessary. I'd thought this would be a good approach if this issue follows that issue's output. Also we get to benefit from the creativity of our community's digital designers. The developers then implement those ideas/designs. More like a domino effect. 😄
