I'm starting to maintain our trade history again and will try to go back and record the retroactive trades (with no promise of capturing every trade). I've also updated the original sheet a bit. The organization name and owner name will now be reflected. The owner name will be the owner at the time of the trade. The organization however will link to the current org name.
As such, if you have editing power, please do not sort the 'Teams' sheet. If this was excel, it probably wouldn't matter, but this is not excel and will f*** up those links.
It will take me a bit to get the trades updated, but I'll work on it and keep new trades updated.
