I have a new team member on the Atlantic team.

Will they automatically show up in the BOINCStats detailed info page (after BOINCStats polls the project servers) or does the person also have to get a membership here to have their data included in the team?

Depending how often the project where your new team member joined the Atlantic team will export the stats, it will be updated on the BOINC statistics sites. Normally within 1 day at the most.
Remember for the BOINC combined stats the new member should join your team in the majority of the teamwide projects,
before he/she will be recognized as an Atlantic team member for the BOINC combined stats.

Thanks for the info. The member is subscribed to all the same projects as myself. It's been just over a day so I'll give it another day or so.

It's not that I don't want my team mates to get signed up here at BOINCStats, I just want to break 'em in easy so they don't overloaded with tech stuff.

You can put up Elysia with some tech stuff

Perhaps she has to have some credits of her own first before popping up in the stats.

The new team member is now reporting that 25.28 credits shows for boincsimap (via BOINC project manager) so hopefully the next update will officially put her on the team. She has also completed some other project files, but they will show up when they show up...

My new team member has been rolled into the Atlantic Team. Excellent, working great. Thanks.
