When submitting an idea, consider these few points;

• We prefer ideas that won't be a burden on a budget. Money is tight for a lot of folks.
• We prefer ideas that are specific. Cooking is great, but it's a large topic. Instead, "perfecting a pizza" would be better.
• We prefer ideas that are easy to pick up for most people. It helps if a tip is relevant for a crowd of people. Not a niche.
• We prefer ideas that make it easier for people to practice social distancing. Content that helps with kids is much appreciated.

Part of me wants to merge this. But another part of me wants to keep this around for historical reference.
