I thought of this idea. I know that each of the four communities listed have members who overlap, but these are the four I'm most familiar with. Explanations: The SALC (Scratch Alphabet Lore Community) is Gryffindor because most of its members used to be part of the NBC, but left for Alphabet Lore. The CCC (Conscript Community Central) is Hufflepuff because they fit Hufflepuff's traits best. The SOSC (Scratch Object Show Community) is Ravenclaw because it is the only of the four communities I thought of that was left for it. The NBC (Numberblocks Community) is Slytherin for obvious reasons. If you are in this community (especially if you aren't also in the SALC, CCC, and/or SOSC), I'm sorry, but your community fits Slytherin the best.
Credit to everyone.
