Mark,
The question is what do you expect as basic knowledge from your audience ?
Perhaps it would be good to add a list of references/index at the top/side/bottom of your page where a reader can get the basic knowledge.
Chime -> explanation and Link to MDL pdf -> explanation etc
As you cannot predict the knowledge and intelligence of your clients, there will be always something going wrong. So, might be that explanation links are the easiest way ?
Hi Michael I do exactly that, see for instance,: http://www.webelements.com/webelements/elements/text/H/xtal.html I don't get complaints, but what I do find is that overall more VRML files - no chemical information :( - are viewed than PDB files. I use a tracker, one item of which it reports is NetScape plugins. Chime/Chem3D are both very low in percentage terms (given that WebElemewnts is a chemistry site), VRML browsers a little higher. Flash is almost universally installed. Quicktime and PDF readers are pretty high as well. One or two other snippets from the tracker that you might find useful: 90% have a screen size 800 x 600 or better NS/MSIE version 4 or better accounts for 98% of traffic - so get your style sheets validated and scrap <FONT> tags etc. Operating systems: Windows 87% Mac 10% Other 2% Unix 1% Browsers: MSIE 76% Netscape 24% Opera 0.06% iCab ? - seems to not get recorded properly in the Hitbox stats Javascript: 97.5% enabled Java: enabled 95% unknown 4% disabled 1% -- Dr Mark J Winter Department of Chemistry, The University, Sheffield S3 7HF, England tel: +44 (0)114 222 9304 fax: +44 (0)114 222 9303 e-m: mark.winter@sheffield.ac.uk http://www.shef.ac.uk/chemistry/staff/mjw/mark-winter.html WebElements is the periodic table on the world-wide web: http://www.webelements.com/ The Sheffield Chemdex is a listing of chemistry sites on the world-wide web: http://www.chemdex.org/ chemweb: A list for Chemical Applications of the Internet.
