I can't understand HTML5. It SEEMS to be server-based/dependent. (?) (I used to use KM in Windows 98. . .)

My question is, without Flash readers, which are said to be obsolete, will I still be able to send a friend a simple cartoon in swf format? Explorer will still open them, but some of my friends don't have Explorer.

I enjoy primitive cartoons with a "Click-and get a surprise" kind of thing. Stupid but harmless.
