Presumably we could put another column in so that people could opt to be kept up to date on what the local group is doing?
The basic form is worded to indicate that by giving us their details, people are assenting to receive further information from the campiagn, so a further column is unnecessary. It is also in our experience likely to be counterproductive, because a "do you want to be more involved" box takes extra effort to fill in, and it will cut down numbers you can contact while at the same time increasing the proportion of impetuous flaky people who turn out to be useless, and discouraging those steadier more thoughtful ones who will actually end up giving more to the campaign.
For the same reason of competeness, and minimising the steps involved please dont transcribe the data and forward it. As soon as the petition forms are completed, please send them to the office, keeping the information you need locally. We send everyone who completes the petition with their address a supporter's pack inviting them to join, and add every email address directly to the newsletter list. It is good to do this while they might still remember signing.
For this reason it is important to get people to write clearly and give their full addresses (inadequate addresses and illegible signatures not only cost us money and time, but they are worthless for the petition element of the exercise - Mr Unidentifiable Scribble is not a valid petitioner. You may find it helps to write a realistic dummy address very neatly on the first line (don't forget to cross it through before sending in the petition). People are subconsciously imitative, and if one signs with a scribble, the rest on that sheet will follow. (So start a new sheet if you spot it happening.)
