How far back for compatibility?

[conundrum7g]

When we design our forums, we can make the most eyecatching wonderful designs.

But what about when someone with an old browser tells you the table that's embedded inside another table is displaying your table cell backgrounds wrong? Or some other problem that exists with browsers as old as Netscape 4.0.

Do you change your code and lose your fancy design for something less attractive. or do you let those old browser display your forums incorrectly?

There is no right answer. But what do designers here think?
