@ignat99 let's refrain from shitting on other team members. Let's keep it constructive. We merged your code to try and move past issues but if you're going to be effective on the project I'd appreciate on us all being civilized.

I'm going to tag this Dont Review for now while you flesh it out and please consider the suggestions. We can't just merge half baked code because it's frustrating to everyone. In understand that language may be an issue here. Please try your best and we will do ours to review your code rather than your English.
