Most active trading guilds have 500/500 or 495+ all the time. They remove members that are not selling or have been offline after a certain amount of time as per the guild's rules. You can only see how many players in the guild once you join them.
Nirn Traders GM (est 2015)
PC EU
Semi-retired. Playing games for fun. Super casual.
The other thing to know about trade guilds, is they don't just trade with members. Usually they hire a trader, and anyone can buy from that trader. Take a look around some of the big centres, likes Wayrest, or Mournhold, or Elden Root, and visit the Guild Traders. You have to use the Search function to see anything; the stores look empty otherwise.
Favourite NPC: Wine-For-All
Mostly PC-EU , with a lonely little guy on NA.
