I, for one, appreciate the efforts you have invested in this forum.
While I understand Andrew's complaint, and I agree with him, I too, have hit the Mark All Forum Read button by mistake and am willing to "suffer" with the confirmation instead of trying to figure out what I marked read by mistake.
I also like the ability to "hide" forums that I never read with the "Mark Read Until" feature. Best thing ever. Of course imnsho.
Carry on...
