I too absolutely despise Thursday maintenance. I just, ONCE AGIN, forgot, while designing a very expensive item, with much research gathering invested, and alas.... LOST IT ALL AGAIN!!! PLEASE figure out a way to save your listing when these maintenance periods start!!
Also, Thursday is a good night to list, so wish they'd get a different night, and much later time in A.M! I think much less people would be listing in the A.M! ... My 2 cents!
