It's awfully handy just in day to day communication too really. I send my partner at least 10 stumbles a day
.. Look at this, Have someone cover this topic.. fix this.. and so on
Be careful with that adult option though, When I first started stumbling, to be responsible I did mark my sites as Adult ... gambling = adult right? ... well errr no. Because if you mark it adult, it will come up in google with the word PORN next to it :O
