I basically stopped tweeting a few months ago. I still get a lot of interesting info from twitter, but I didn't know what I was contributing anymore.

TFW you get up at 7am whilst on holiday to finish an application, then rather than sending properly it just silently sits in your outbox over the weekend. 😕.

Ugh. Council elections, how do they work? What I want is "No Tories". I have 3 votes to distribute amongst these candidates. I'd like to do a 2:1 between Lab:LD, but how am I supposed to know which are the 'lead' candidates??
