Added to OPjordsta95 - I'd like to file the name "Team Shinonome". For now, I'm going alone - by which I mean I'll try to find more people by Oct 31st (yes, feel free to ask me if you want to join). Also, a polite request: please anonymize entries for voting. Since we are trying to judge based on pack merits and not popularity, it makes sense to not make it straightforward as to who made what pack.
I recommend you do it how the MegaZeux community used to do it for their game contests: on 1st November, you assign every team a random number from 0 to 99999 and they have to use that number to identify themselves. On voting, every pack is named like that, with no mention of the authors. After the results are published, the numbers are linked to the respective teams.
As for voting what I am thinking of right now is there will be a single thread (in the 3rd party packs sub-forum). In that thread there will be a section for each pack. Each team will send me the whole description for their pack and it will be added to the thread into a spoiler for each. And the only thing to identify the packs will be the pack names (before the results are released, whoever send the pack off to the FTB team will need to just put author as "team <number>", I'll send off the details to everyone in more detail on the 31st )
Example of the forum thread:
<introductory text to the challenge along with the rules and the teams involved>
<pack name> by team 1:
Pack code
Whatever team 1 sends to be added
link to mod list (google doc/spreadsheet)
Whatever team 1 sends to be added
link to mod list (google doc/spreadsheet)
<pack name> by team 2:
Pack code
Whatever team 1 sends to be added
link to mod list (google doc/spreadsheet)
Whatever team 1 sends to be added
link to mod list (google doc/spreadsheet)
etc. etc.
Link to google form for voting (undecided on how voting will be done - 1 criteria, or multiple criterion; mods? interaction? playability? etc.?) This would be added after a month or so
