I have a choice of host with the forum I'm developing (i'm purchasing and migrating a phpbb forum) and I wondered what opinion was for Linux or Windows? I am an ecommerce developer mostly, and know the cross benefits of zen cart on Linux or Windows.. wondered if UBB was the same?

I'd recommend Linux personally... And I'm sure there are some who'd recommend Windows ...

Go with Linux.

I have run these forums on both OS's and I can honestly say I like Linux way better as far as speed and dependability.

Cheers all. I have got to say I was leaning towards linux based on my previous luck and experience with my previous PHP sites. A client once had 1&hosting with 1&1 and it was a nightmare on Windows. Its rare to get a green light on all settings you need enabled when installing on Windows...

windows is more forgiving in the directory perm side, but that is the only 'advantage' if you even call it one..

linux wins, hands down in my book..

1&1 isn't just a nightmare on windows, their service sucks; outright...

Linux does not require the overhead that a windows server does. You can generate more speed and reliability in Linux with less resources then you can on windows.

Linux

linux. but that could be the old man in me talking. if you are not comfortable operating your server with command-lines, then you maybe better off using Windows®
