Is there any other information you think would be useful to include in the file? Please add a comment below.
The usual words of caution apply... it's only accurate on the day it was published... prices go up prices go down.. new organisers appear... some disappear
If anyone would like to volunteer to help me maintain this file I would really appreciate it, diving between three different websites is confusing and time consuming! If any of you could just keep a check on just one of the sites (UK, US, France or Germany) that would be a big help. I can share the Excel file with you using Dropbox so it makes it easier to keep it up to date, without needing to email it back and forth.
