Maintaining shared pages on www.tcm
Maintaining research grouplet pages and similar on TCM's web server is extremely similar to writing your own personal page. It is, actually, even simpler, as the included files should not have the "_personal" bit, and there is just a single footer, so that the basic skeleton looks like:
<!--#include virtual="/includes/head.html" --> <title>Page Title</title> <!--#include virtual="/includes/menu.html" --> <h1>Page Heading</h1> <p>Put your content here.</p> <!--#include virtual="/includes/footer.html" -->
Of course, the same simple markup as is described for profiles applies to these pages too. As with personal pages, one will also wish to consider including images.
Images required by the page should generally be put in the same directory as the source.
Links to "quality" external sites are encouraged: they will boost the ranking of the page in most search engines.
The file itself should be maintained formatted in a way that is easy for other humans to read and edit: blank lines after paragraphs, lists, titles, etc., lines generally limited to about 80 characters, and UNIX-style line endings.
JavaScript is not encouraged, not least because it reduces the number of people who might reasonably be expected to maintain the result.
