Chat log question

1. Is there any way to only download the most recent entries? 2. Do I need to log in to access these log pages? Can I use a script to read the log? Basically I'm trying to write a local script that reads my players' responses and auto-resolve some combat chores (to-hit roll and damage roll, keeping track of spells' duration, keeping track of initiative order, to name a few), but I'm also aware of the possibility that this may levy a burden upon the roll20 servers. I'd appreciate any suggestions and pointers. Thanks!

Gee, thanks! That's very encouraging :) May I ask which language should I expect? I'm currently writing my script in perl, could probably pick up C again, but really could use a head start for any other language. Again, thank you for your great work! Roll20 is like one most wonderful thing that had happened:D

Could future alterations to the chat window allow it to be completely hidden?
