RE: Input for survey about random sampling

Dear all,

Please find below a new version of the survey with changes made after our Telco. I also tried to work the comments received through the mailing list into the questions. Hope this would be ok. Think it would give us a good overview of activities. I added a number of yes/no questions to make it easier to calculate the results...

Should we also add questions about the person answering the questions?

Please send your comments to the list before monday evening.
