Now bear in mind that I'm British so I should be saying "this is rather good, chaps", but in fact it is awesome!
I've signed up to SciStarter so I can contribute to scientific research from the comfort of my own home. There are so many interesting projects listed, including Notes From Nature (transcribing labels of historical museum collections) that I've got bookmarked to contribute to when I have more time, and Treezilla (mapping every tree in Britain) but I was disappointed to find projects listed that had finished, and projects that involve further registration instead of the SciStarter login being sufficient.
I have just taken part in the VerbCorner Project, answering questions about the use of words. You can login or take part anonymously and it's great - challenging enough to be interesting, but not so hard that it is demoralising. So thank you SciStarter for linking me with the project and making me feel I have contributed!
