Hello to the great and good

Two questions;

1). A userform shows for 10 seconds (workbook open event) before being
unloaded is it possible to show a count down clock on the userform and if so
how. (code clues appreciated)

and

2). I have a userform created in VBA and I was wondering how to put a live
mailto: link in? Currently I have the email address on the form in a
textbox... but it doesn't work!

TIA
