AutismChat 3 is far from finished. I would say it's in Alpha currently. When I get the .jar file tomorrow (hopfully) I will be able to (time and energy permitting) start playing with the formatting and with the help of my team of bug testers (Cassolotl, Jazzable, MowLiao) identify more issues that were difficult to identify without access to the server file system.
Richard, the plugin developer has said that he will be willing to work (for money) on new features that weren't in the original specification. So essential features that are currently missing (e.g. a way to find out who is in your party without having to leave it and rejoin) will be added. There will be a github repository to make issue tracking easier.
If you would like to play on the AutismChat 3 test server which will disappear in a month, log on at 185.38.148.190:25586
There are currently no plugins apart from AutismChat 3, and there are no admins.
At some point, perhaps in a week or two (depending on what issues are identified and how long it takes to resolve them) I will say that AutismChat 3 is ready for Beta testing and tentatively endorse its installation on This Land. Of course, Cassian may have already installed it; they are very impatient.
