Finally, I managed to get the new rsyslog site up and running. It turned out to be more work than initially expected. Special thanks go to Timm Herget, who did some of the initial preparation and of course to Andre Lorbach, who made the whole system appear. I just added the content and fumbled a little bit with the config settings ;)
The new site now allows user postings and easier updates. I hope it will be a valuable resource for the (hopefully growing) rsyslog community.
Besides rsyslog, the site also is intended to provide reference for add-ons like phpLogCon.
