Dear colleagues You may or may not find this helpful when considering designing your chemistry site. The following are results from 100000 accesses on 1 page of WebElements over the last 20 days or so. They were achieved using the free www.hitbox.com service. No doubt there all sorts of systematic errors so don't take the numbers too literally. Browsers Netscape 52% Internet Explorer 47% Others 1% (mainly WebTV) Versions 5.x 1% 4.x 70% 3.x 27% JavaScript enabled: 96% Java enabled: Yes 80% No 6% Unknown 15% OS Windows 83% (95 53%; 98 18%; NT 9%; 3.x 4%) MacOS 14% Unix 1% WebTV 1% Other 1 % Screens 800 x 600 45% 640 x 480 29% bigger 25% Plug-ins (as % of accesses) QuickTime 39% LiveAudio 38% ShockWave graphics player 38% NPAVI32DynamicLinkLibrary 27% (what is this?)

They do seem to suggest that if you have a controlled audience (that is, a group of your students, say), then assuming specific plug-in availabilty might be OK - but if your audience is general, then assume very little !
