38 Degrees is a great online campaigning organisation.

As they told me in an email this morning:

Dear Richard,

Thousands of us have decided what 38 Degrees should do as the government plans cuts. Together we're going to push them to crack down on the billions we lose from tax dodgers every year.
Right now Chancellor George Osborne is deciding what he'll cut. We're all going to be hit by the VAT rise in January and less money for services like schools, hospitals and the police. Every year a selfish few rip us off by dodging billions in tax. It's a big problem - the government says every year we lose at least £42 billion in "uncollected" tax.  The government needs to stand up to tax cheats and make sure everybody, including billionaires, bankers and media moguls, pays their fair share.

So here's the plan. This week we're launching our "Crack Down on Tax Dodgers" petition to pile the pressure on Osborne. Next week, together we'll start work on hard hitting adverts to publicly shame the Government into taking real action. Then as our ads are hitting the media we'll take the campaign to Parliament - so everywhere Osborne goes he'll be asked "what are you doing to stop tax dodgers?"
But time's tight - the first thing we need to do is prove this is a big issue amongst ordinary taxpayers. Help make this petition massive so the government knows how many of us want them to "Crack Down on Tax Dodgers". Sign the petition now:http://www.38degrees.org.uk/crack-down-on-tax-cheats

The government likes to talk tough about catching benefit cheats. But it doesn't make sense to only target benefit cheats when tax cheats cost us £40 billion a year more.

Some politicians have made grand speeches about tackling tax dodging. But they haven't turned their words into concrete action. We need to show the government that tough talk isn't enough - we need real action. Sign the petition in 30 seconds at: http://www.38degrees.org.uk/crack-down-on-tax-cheats

We've got a huge amount to do to pile the pressure on Osborne before he announces his cuts in three weeks. We've made politicians listen before and we can do it again. Earlier this year we helped persuade Osborne to make the rich pay their fair share by increasing Capital Gains Tax. Before then we persuaded the previous Chancellor to stand up to the banks with a windfall tax. Already this year 25,000 of us have shared our stories about why protecting the NHS is so important.

Let's force the government to crack down on tax cheats. Sign the petition then forward this email to your friends: http://www.38degrees.org.uk/crack-down-on-tax-cheats

Thanks for getting involved,

Johnny, Hannah, David and the 38 Degrees team

PS: Osborne will be making his mind up about what to cut very soon. That means we don't have long to prove how many people think the government should crack down on tax dodgers. Click here to sign the "Crack Down on Tax Dodgers" petition now:  http://www.38degrees.org.uk/crack-down-on-tax-cheats

I guess it’s only right I disclose I have been advising the 38 Degrees team on this one.

But that’s even more reason for me asking you to please sign the petition.
