Update your web content per developments since you first created a schedule a month ago.
If you have a web site not hosted on this wiki, create an interstitial archival page on this wiki for your project, and populate it with enough content to be reasonable. Update the Projects to point at the new interstitial wiki page.
After you design a poster, output a PDF version, and link it to your wiki page using the Attach:filename.pdf tag. If you wish, you may upload the PPT or PPTX file for archival purposes too.
If you like, you can output a PNG of your poster as well, and have most of the content of the wiki page for your project be a PNG image of the poster itself. If you do this, output a PNG that's about 800 px wide, so it can display nicely on a web page.
