2 Quick Scripting Questions

Hi, I just have a couple of questions for an ASH script I'm doing.

1) How do I find out if an area is accessible? I.e. I might be level 11 and have got the Fantasy Airship quest, but I don't necessarily know if I've used an enchanted bean to access the Airship yet.
2) How do I find out if a certain quest has been given to me yet?

1) It depends on the area. Generally, using visit_url() and contains_text() will do what you need, occasionally with item_amount() thrown in.

2) Use visit_url() and contains_text() on the quest log
