Write it on the wiki first then just email the link to the wiki. No additional effort and then the guy who joins two years after everyone on the email chain has left and now has to maintain it also has that info.
I meant specifically, things like "Wait, who is this person? What did they want again? What did I tell them last time?" That's not stuff you put on a wiki.
At the volume of mail I was receiving at Google (100+/day), there's just no time to manually index things like that. Why can't we let email archives just function?
