Chubsasaurus, sorry if my post was the last thing you wanted to see after a long day. But I had already sent it when I wrote about it on here.
Clearly people do need to be able to write to MPs, and even though I didn't phrase the email myself, it said what I wanted to say. OK, it's less effort for me, but it's just as strongly felt as if I had spent 6 hours on it. Why would it have meant less work for you if I had written it myself, btw? Surely if lots of people send in the same email, you can write one standard response?
Also, the 38 degrees campaign is run by people who are doing something to change things they feel really strongly about, probably for no money and in their own time. I know political activists also stay up till the wee small hours - unpaid - and their campaigns are a great way to get people involved, imo, even if in a small way.
But getting home at 10.15 is no life for you. I hope you're taking some time off after the elections? 
Oh, and if you are working for my MP, don't out me on here when you get my email!
