I am planning to develop an application on Maemo 5, but i need some advise.

There is a community site based on vBulletin Version 3.5.2.
I want to be able to get the messages out of the inbox and be able to reply on the message. I would like to know what is required to log in and read and reply messages.

Do I need acces to the database ?
or is there a function to read out a page and take out only what is neccesery ?
