Don't let the forum put you off. To be honest, am annoyed at how ignorant people are. For example, "How to change Splash Text" in different posts and they did not bother to use search first. Hence, those type of people would just go ahead and update to beta and then start complaining.

Another good example... do you always agreed with movie critics? Have seen 2-stars rating movies and thought those movies were brilliant and should be 4 or 5. People have different taste, perspective, or whatever.

Have you tried UNA? If not, how can you possibly know? Wordpress supposedly to be the best according to popularity. Have tried it and fooking hate it! Tried Joomla, don't like it as well. So, don't be afraid to try variety of platforms and then you can decide.

They are not forcing anyone to upgrade to beta. Have several domains that's running in stable version 10.1, only one running in beta (11.0.0-RC2) for testing/reporting. Been with them since 2009 and am still loyal! I even helped shape UNA such as OpenStreetMap which will be default (future upgrade), Font Awesome version shown rather than hush (11.0.0-RC2). If you have idea/suggestion... maybe UNA will bring your wish to reality.
