Like System
The like system has been successfully installed! This does mean the reputation system has now been disabled. We are aware that there isn't option to unlike a post if you accidentally liked it for example and that it may look a bit untidy with it being placed outside of the post.
We are looking at sorting that when upgrading to the "Pro" version of the plugin. Which hopefully may be in the near future.
Other Stuff
The "Last Edited by" bug which was showing random usernames on your own posts should be fixed and any other problems with phantom reputation, mentions and quote notifications.
Also a thanks goes out to @scottish; who helped us with the above.
