Alright, so thru experiment i found first number in this function is number of signs to skil from the beginning and the second one is the sign number to end on. Thanx to that I can set post length to a static numbet to end on a specific place in my post. But this still doesnt’t satisfy my needs. Other posts are going to have different placements for end of my intro. I want this length to be dynamic, depending on the <!–more–> tag in my post. I bet this is a difficult task, but i hope mayby there’s that function in Appointment theme?
