I've played with an old FF extension that lets you right click on an article it will submit to your pligg install with fields prepulated.

I couldnt always get it to work smoothly and of course it doesnt work on FF3
Anyone know about about a FF3 alternative?
Its the sort of thing that would sell well in the pligg pro shop.
happy to pay if someone is thinking of developing
thanks
