I agree with regards to collaboration, however practical criticism is ignored or frowned upon. Simple spelling mistakes (never mind grammar) even go ignored.
Though I do use CWP on 'live' servers, I'd NEVER trust it with more than just a few sites, that I could migrate to cPanel/DirectAdmin/Keyhelp/ISPConfig very quickly. Lack of confidence?
There are and have been numerous issues with the backup features for much more than a few months. Issues with fundamental features appear to be ignored, in favour of more frivolous ones, such as Shoutcast/Teamspeak/Netdata/whatever.
(I'm sure that I noticed someone else mentioning problems with incremental backups, in another thread/topic.)
