and I try in IE6 but the modul doesnt working... Could you help me ?

In firefox,chrome,IE7 + works good ... :(

Where is your site?

IE6 has some major deficiencies in CSS support, so some simple styling techniques will not work in it. It often requires a much more complicated set of code to get the same result.

But realistically, is it worth it? How many people are still using IE6?

At this point, it would depend on the target market. Some corporate computer systems are still locked into IE6 because they had programs custom-built to depend on it, and anyone with a Windows 2000 operating system (which can still perform fine for modest use) will be unable to upgrade past IE6.

But realistically, is it worth it? How many people are still using IE6?

gih32 is correct about corp use but if that is not your target market then you can have a look at these stats
Doesn't tell who they are but even 5% of how many million users ?? is a large number
