You're right. It's been MIA for over a week, no drop down menu to the Classics. The way I access it is to type the name of the poet into the address box, like www.allpoetry.com/Gelett_Burgess Or else I google the poem I am looking for and sometimes you will see the AP version come up, as long as you add the word "Classic". I suppose it is all part of Kevin's game of psycho manipulation that the "think tank" out in Palo Alto is studying. [well, that link doesn't even work; I must have mispelled it.]
It's listed under the Allpoetry logo, a drop down menu appears and you just click the Classic Poetry line. That will take you to oldpoetry
Of course they do, whoever they are.
The mods + greeters are currently beta testing some interface tweaks that will make it easier to browse old (classic) poetry, among other things. I hope to make a public beta test of it in a week or so.
