if I know I read through ep 890, therefore, I'd next want t read ep#891, why, if I"m in Robservations, can't I just put in ep#891 (I'm trying to type it how it reads on the board).
Most (though not all) of the Robservations are in order, so using the "previous/next" options at the top right (above PRINT) will often take you to the next pair of eps. Robservations for #890 and #891 are on the same page, and clicking previous will take you to #892 and #893, clicking previous for those will take you to #894/5 and #896, and on and on. And yes, we do realize that the previous/next buttons have always been misnomers.
If the previous/next links do not take you to the following/prior eps, the Search feature will be your only option.
