Re: Loading times
The fade does not effect the server. All the server has to do is send about 40 more bytes of data (which is just the meta tags - normal HTML). After that, the browser reads that meta data and if the browser is IE, then it will understand it to make it fade in and out. Once it understands it, all it has to do is make the effect, which is all client-side.
It doesn't put anymore strain on the server. Having that in each headerinclude template is much less of an impact than even posting 1 character in a post or viewing your UserCP.
Happiness is not about being perfect.
It is about seeing beyond the imperfections.
