I for one (and being very green here) can never find the 'Writeup Formatting Tips' link when I need it. It seems to come and go with the wind and I probably don't take advantage of linking other nodes because if it. (oh, wait, there it is at the bottom of the page :s)
It would be great if the message composer had a row of handy 'fill in' buttons for things like linking to other nodes, other monks, the usual text modes and special characters. This is the web after all?
