Certain features, like reading posts unless you're signed in... To me that = closed since the majority of users are lurkers on most forums. Regarding headers you are absolutly correct. However the headers are indicating the server software being used. Experience tells me this software is heavy on server resources and therefore not an ideal fit for web hosting on a shoe string budget. And yes issues certainly exist with the 'web server config' and possibly the database config that could be addressed to hopefully keep the website online and open for visitors during usage peaks.
