EU Referendum Campaigns - which one?

Am I the only one who is currently a bit confused by all the EU referendum campaigns which are currently running along side each other? To date I can count;

• The People's Pledge
• EU Referendum Campaign
• The EU Referendum pledge

Now as far as I can understand these three bullet points are all interlinked in some way. But I am not entirely sure how, all I know is that it is very confusing and if they truly hope to consolidate and concentrate support then surely that would be a lot easier with ONE website and not three.

If anyone is in direct relation to the campaign please forward these concerns to them.
