I read a few months/weeks back about a site you could use to stop you accessing certain websites during the day. E.g. blocking facebook between the hours of 9 and 5. I can't find the original post and NEED this website if I am to get any writing done this week, I spend hours just looking at facebook/forums/news websites and need to stop!!

Does anyone have the web address??

I think you're refering to the Firefox add-on called 'Leech'.

It's very helpful, but can be circumvented easily. Nevertheless, still very useful.

Here's the thread. I posted it awhile ago and have used it ever since. It's definitely working for me as it has massively reduced my procrastination during the daytime (when I set it to operate). I have a one hour window at lunchtime to surf my procrastination sites (which is why I'm posting now!). Make sure you have Firefox and uninstall/disable Internet Explorer if you can (so you can't cheat). Then set Leechblock to its highest security settings so you can't hack it when it's operating. Made a big difference to me as it makes me work and once I get going I can generate some momentum. Anyway, see how you go!

Thank you! Will sort it out today, hopefully this will mean I get my supervisor his work on time.
