I couldn't help wandering over to https://openacs.org/community/sites/ I noticed a couple of listings by companies that don't seem to have any involvement with OACS. It may be wise to clean up the page.
On a diffent note, it would be usefull to change the ETP format so contributions are displayed A-Z instead of date of entry. Should I report a feature request in bugtracker or is this allready solved?
