When you are customizing and tweaking your forums, do you remove unused code/functionality.
An example of what I'm talking about. As I was changing the layout of my site, I was changing around inc_header.asp. I was moving the navigation to the left and leaving the login info more or less where it is. I came across the code for NT authorization. I know that I will never use this functionality.
So should I remove this code? If so will this improve forum performance. (that's not my main objective, forums runs fine, more inquisitive).
Just curious more than anything else. I realise that with the more customization I do to the code it becomes increasing more difficult to upgrade or to even fix any new bugs or possibly introduce new bugs.
I don't advise it. Having a couple of features extra does not harm much on performance. In the past I found myself needing some of the features with passing time although I never thought of them before.
Mainly your suspicions on introducing bugs and making it difficult to upgrade are correct. Also some of the MODs refer to code portions and line numbers, so you may get lost .
