Hey,
Na I totally disagree with that. There is no excuse for sloppy HTML. NS just doesn't let you get away with things that IE will.
There is still a substantial amount of internet users who use NS. Not catering for them is like shooting yourself in the foot because you simply won't have the NS members you would otherwise had.
80% of most IE/NS browser problems are due to incorrect nesting of tables.
I suggest you run your Header and footer code (which u put into your UBB General Settings) through this HTML validator
http://validator.w3.org/ This should help you find the errors and correct them.
BTW it's good HTML practise to put "" attributes. For example
instead of Also to specify alt tags.
