"I shall contact..."
or
"I will contact...."

"I shall" all the way now....

Oh I've been taken too much work on of lately!

I still have MN open on one window on the computer so I'm here most nights but don't have the time to contribute to any threads. but I'm keeping an eye on conversations!

I still have to work over the whole of easter to keep on top of things but can only do it at nighttime when DD is asleep. i even missed Desperate Housewifes this week because of it!!!
