There are many people who make little discoveries or re-discoveries in the criteria of Maths and they want to share these with the world. A convenient way to make this available would be the creation of a subsite of Math.SE where members could share their discoveries from little to bigger level. Experts on this site could judge their work, detect their flaws and correct them. Votes would honor the inventor and it would be a source of motivation. It will prevent Math.SE from getting off-topic questions also.
