Hi guys, when browsing very long discussion threads, it would be nice to have a button or link that quickly moves to the top of the page. Currently I have to use the vertical scroll bar or mouse wheel. Sorry if this has been suggested before (I didn't follow this forum closely). Thank you!

Here's a quick and dirty solution to the following task:
Arrange digits 1,...,9 so that the first two form a number divisible by 2, the first three form a number divisible by 3, etc..

See Joe Riel's blog for more information.
