I may be proving myself extremely dim...

...and if I am feel free to give me a good clip round the ears for missing something obvious, but how does one go about getting a Mosaic 'published' as it were? I know they aren't commissioned by IDW or Hasbro, or published in any physical form, but presumably there's some procedure to which ones go up on the site, otherwise we'd would surely be inundated by them. Thanks in advance for answers to what may be a stupid question, but I've failed to find the solution anywhere else.
