. TAG
Are you teaching a course related to Web Architecture? Do you train webmasters? The TAG encourages sharing educational materials of all sorts, from exercises to articles, to slides and presentation materials.
If you have something to share, please let us know! We intend to review materials on a best-effort basis if you send a pointer to www-tag@w3.org (a mailing list with public archive). We hope you will be able to address any comments that come up in the course of our review. We're interested to know about the audience of your materials, the terms under which other people can use it, whether it's actively maintained or just archival, and so on.
This is a product of the W3C process, so it has had a lot of review. It has a number of examples, but it is written for a fairly technical audience. A PDF version is 42 pages (see Norm Walsh's explanation of how it's produced).
