I've been at school since I saw your post. I'll get you set up about 3 hours from now, when I get home
Ruatha has summed it up pretty nicely.
The details;
Each turn, I post a link to the savegame in the Newspaper stand. (Look for the 'Latest news about the world you live in" thread)
If you have SE4gold, you can open the file directly. Be sure to have gold patch #3 installed, as well as the committee mod, or it won't load properly.
A link to the mod is in the same location.
http://imagemodserver.mine.nu/committee is the place to get all the stuff you need.
I have set up a special "Orders Submission Forum" at the bottom of the PBC Boards. Players are allowed to post, but not read.
Due to that, you can't go into the forum and press "add topic" or "add reply". Instead I have written intstructions on how to post to that forum in the description of the Forum (on the main page of PBC)
Make your instructions clear, and as literal as reasonably possible. I will do my best to interpret it, but the less I have to guess, the happier you'll be with the results
"Move 'Blade of Ruatha' to Avalon (6,6) and Destroy Star", for example, or "Add 'Temple of Aaron' to the build queue of Calonica Primus (A well known planet) at Emergency rate"
Even if you don't have SE4 Gold, you can play; there are screenshot maps, and plenty of people to ask. I can even post or email local event reports for players who need them.
