Here are the key new features of OpiWiki:
Extended LayoutI've already talked about how special OpiWiki's layout is. Now it has become extended – not only in terms of the size, but also in terms of having even more amazing fonts, new icons and solutions. I truly love how pages with little to no images look like a piece of unique art, but at the same time they're elegant and clear.
Superior discussion systemThis one I worked on for a long time; I wanted OpiWiki to have the best environment for discussion of any website. Now loading further replies or replying to talks is always done without refreshing the page. For opinions with multiple replies, it all clearly lays out, with lines, arrows, and hints to guide the reader. You can now subscribe to any talk, or send a challenge to OpiWiki user(s) to reply to a certain talk. Example topic with many talks: Should prostitution be legal?
ChallengesIt's now possible to invite OpiWiki users to answer a certain topic or talk. If you're interested about some user's opinion, simply go ahead and send him the OpiWiki challenge. Feel absolutely free to do so – it's just an invitation, and users can disable the possibility of inviting them at any time.
New subscription systemPreviously it was possible to subscribe to topics and opinions with much less options. Now it is possible to subscribe to topics, opinions, and replies, but also to categories and tags. You receive neat emails with new opinion, reply, or topic notifications, depending on your subscriptions. It's fully customizable, e.g. you can set how often you'd like to receive emails, or disable email notifications and use OpiWiki inbox only. From email, you can always update your subscription or unsubscribe with one click without logging in.
Item tagsMost of OpiWiki items have now their dedicated tag. Item tags are being automatically created. Thanks to these tags, it's now possible to subscribe to items as well, to get a notification when a new related topic is created. It's also much easier to find topics related to a certain item – you simply search for this item in "Tags" on pages like OpiWiki/discuss or Categories.
Categories and CustomizeThe Categories section has been improved. This is now the section a user is redirected to after creating an account. The user is asked to subscribe to his favorite tags, which is a very smooth process. In general, I love how smooth and useful this page is. In combination with our great tag system, Categories lets users find topics they specifically like in a few clicks.
Related feature that has been improved as well is OpiWiki Customize. A user selects categories their like to customize their home page, and optionally subscribe to them all with one click. These settings are also valid for the Newsletter.
