I've dealt with professional coders before and they do test it locally. If an error pops up due to different settings and specs of a server, it's easy to fix. A PHPBB mod probably wouldn't run into said errors if it were tested locally on a local PHPBB forum.

But anyway, this is none of my business, I just wanted to express my opinion.

I doubt iL < had any malicious intention anyway. (GL with your sales man)
