Might have been a god idea to do this in the beginning, hovever I do not expect to get many more answers so adding it now will probably not leed to any reliabel results. in fact I think the total number of answers will be so low that it will be impossible to devide the sample into subgroups and still have enough answers in each subgroup to get reliable results.
Also I wanted to keep the number of questions as low as possible in order to encourage people to participate.
