RE: Talking a Little Bit About Guilds

Starting a guild for leomarkettalk seems like a good idea. I'm sure there are enough regular commenters there which also play the game, and some may not be part of a guild.

No, there's no SPS cost associated with creating a guild. As you believed, yes, it is about the SPS airdrop. Because holding DEC (liquid or in a supported liquidity pool) gives airdrop points which boosts (somewhat) your daily airdrop.
