[2008] App that connects to a Forum w Login/Pass

[Quivver]

Hi all,

How would I go about writing an app that connects to a web forum (phpbb / vbulletine) ? I have built the forms, controls and other aspects of the gui and done all the validation, but am now facing an obstacle when it comes to connecting to a particular forum by passing both the username and password.

ultimately i want to be able to connect to 5 forums that i am a member of, each with a seperate login and password set and then post a single message. The challenge at the moment is how to pass the password and username to the various forums, and also how to proceed once i have connected to a specific forum (or subforum) which i only know by name. i know web forums have forum id's which can be accessed by php (but only if you are an admin) but how can i access say the .net forum on this particular forum and post a post here ?

Any hints or other useful suggestion would be most appreciated.

Thanks in advance,

Quivver
