Is there a way to turn off the iPhone app and just go to the regular website?

 

Can't please everyone, can't we?

For the regular web site, just use Safari, Chrome, Firefox, etc. and go to:
https://5series.net/forums/

If using the iPhone IPB app, the bottom right corner has an icon for "Open in Safari".

Thank you, Lomag, for upgrading to IP.Board 3.2.1.
