Something I love about the online campaign ... I do tend to create my campaign as I go along, describing the interior of a particular inn, giving it a name, the moment it is found. I don't have a list for those things ahead of time, but they come dribbling out of me constantly in every running.
But with the online runnings, there is a record ... so that if the party ever goes back to the town, I can look up to see what features I gave that town on the spur of the moment.
It's a shame this is impractical do to during a normal D&D running - it's too fast moving, and even if I videotaped myself, it wouldn't be something I'd want to spend hours combing through.
Another reason I need tons of money for a secretary.
