I switched in 2009 after the vB4 release and their interpretation of 'Gold'. I didn't see any perspective for a better ending and unfortunately (competition is always a good thing for customers, but they aren't anymore) I was right. vB5 is a disaster and won't be a competitive product in near time. It only has a chance if every other vendor will stop working on their own product.
I've never had a bad experience with their support, though. I bought my license on the Germany sister site and they have been always helpful. Even after they had been kicked for vB5.
I switched in 2009 after they had released vB4 in a incredibly bad condition. I didn't see any perspective for the software and unfortunately I was right. vB5 Connect has less features than vB4 and is in a similar bad shape than vB4 was at release.
So simple: vB5 has no perspective and doubt it ever will.
You can increase this value in main config file (e.g., /etc/my.cnf) using this syntax:
If you are on shared hosting, you can't.
You can edit the name in applications -> Applications Public title.
Or you can add a phrase core/public_global appname _display_title where appname is the name of the app. So for forums it would be forums_display_title, for Nexus nexus_display_title and so on. With the phrases you can add translations for more than one language.
