I was checking out the Area 51 list of participants in Gaming, and I noticed that, for some reason, I'm not actually listed there. I've gotten 183 reputation with 8 posts (and perhaps, in something of a
bad omen tradition, my non-applicable Meta reputation is higher from the get-go), so it is not as if I'm inactive. Furthermore, there are users who have had no activity at all that are listed. I've checked both under the reputation sort and under activity sort, I'm in neither.
Also noting, the question count and answer rate on Area 51 do include my content, so it knows about my contributions, but not the user behind them?
I checked the email for the private Beta, there wasn't anything that seemed to indicate that I needed to submit anything or go anywhere to participate. I've logged into Area 51, and used the "Visit" link to go to the Gaming site and that also hasn't changed anything. My email address is confirmed, too, as I have +50 on Area 51 for it. And it isn't that I'm logged in and it won't show me, as I first noticed this while I was logged off.
The user count on the site is 3 higher than that listed on Area 51, so I'm probably not the only one. What would cause someone to not be listed?
