Thanks for your replies.

Ok then, I'll do as you say - list the alternative fonts (frankly speaking I didn't know what that set of fonts did untill now, thanks). What do you think will be the best alternative for Lucida Sans:

font-family: "Lucida Sans", "Geneva", "Georgia", "Verdana", sans-serif;

You say it's possible to use flash to help me - how does it work, is it difficult to do?

Thanks in advance.
