I have recently been re-exploring Modx because of its context switching which enables me to have several sites in one admin page all with their own page trees. It also has better widget capability (but thats another issue). However Modx soft coding despite being complex and powerful is also cumbersome and rather slow.
How would one go about having two or more page trees in SS3, each responding to its own url. I am guessing with holders but I dont know how. Some guidance would be appreciated. I dont want subsites as such. I want them all in the same admin tree.
