Sorry for the late response. You are allowed to have other devs listed on your plot, but you must be the one to have done the majority of the code. We understand that you may need someone else's help for a part here or there, but besides that, it must be all you doing the code. Builders can be anyone, as we judge the plot purely on code. We also like to see a variety of code, so implementing many different code blocks and features. One of the biggest reasons people can get denied is that they show proficiency in only one area.
