Thread:Project:Support desk/Should I use CentralAuth or shared tables?

I would like to create a global login for the various Sturmkrieg wikis, which will include wikis for each language, and for different gaming related topics. I already have been running the English fanfic/player content wiki for some time now, where as the other wikis generally only have a single admin user account. (de.sturmkrieg.com has a few I believe.) With that, it seems that it would be better to use shared tables, and just stop using the old accounts on the other wikis. The problem though, is that the main English Sturmkrieg has several blocked spammer and troll accounts on it, that I would prefer no have access to the other wikis. I think there's something like 12 or 15 spammers and at least 20 troll accounts. The latter appear to all be the same person, based on Check User and Lookup User information. It would be very time consuming to block them on every wiki and simply changing their email and passwords to prevent them from logging in would be tedious as well.

We also use ConfirmAccount, so I'd like to make sure that will work with CentralAuth

Also, I need to make sure that user renaming would be able to work with the CentralAuth. Would renaming the user on all wikis be an easy way to make sure that the user maintains global login under one account without having any additional action on their part?
