Need a forum with user integration

[comtwous]

Want to build a forum (name it `F`) for mobile web application so that:

* a registered user on my existing website (name it `W`) can log in onto `F` directly using the user ID and password pair registered in `W`, without registering again on `F`. Didn't come up with an example to proof the concept yet. But the business logic should be roughly like this: a user log in website `W` i, click on a `Go to Forum` button on his or her setting page, the `F` forum page get launched in mobile web browser, and the user get logged in the `F` forum automatically with information registered on `W` website, which can be user ID and password pair, or the cookie, if possible, and so on.

* mobile devices such iPhone and Android phones should load pages on `F` naturally. [MacRumors forum](http://forums.macrumors.com/) serves as a good example: we get mobile styles when opening the forum on mobile devices.

Have investigated into vBulletin 5 but seems like it's not so good at doing the above things. Has anyone implemented the above like forum using vBulletin 5?

For the first, you would need to write a bridge between the two softwares in order to allow them to register with one, login with both.

For the second, vB5 works on mobile, so I'm not sure what you want - a totally different mobile style? If so, you may want to use vB4 instead which comes with a separate mobile style.

Thank you for replying, Lynne.

Can you give some more hint about the bridge? Is it a general topic independent on vBulletin, and should be implemented by my own PHP code?

It'll be okay if vB5 works on Mobile. I don't need whole new mobile style, just some appreciate mobile adaptation, such as bigger font, instead of showing the exact same desktop version.

You can take a look at this one here - https://vborg.vbsupport.ru/showthread.php?t=205388&highlight=bridge It's for 3.8, which is totally different from 5.x, but you can take a look and see the code and what they did to integrate the two separate pieces of software.
