Bev,
I got the letter for this project 95% written but then realized that I didn't have the 0&M agreements yet. Then the
consultant sent the 0& M and then I absent-mindedly forgot to complete and send out the letter. Anyway, now I can't
find the 0&M anywhere and it's not in laserfiche so the consultant emailed me another copy this morning.
SORRY about that!! Thanks for the heads up about the letter being missing and for updating the file now.
Thanks,
Annette
