you can now test out an alpha of babble v3.
there will be bugs with it, uploads do not currently work (they will upload but they wont attach to the topic) and a lot of the commands are still out of commission, edit/delete don't work (well they sorta do, but its not a permanent thing yet) .
whispers and private rooms should work without a hitch.
oh you should also be able to use markdown along with bbc in the editor error, so give that a go if you know markdown.
so if you find anything that i haven't mentioned here, please let me know, as i'm pretty sure i got all the features i wanted to add in, now its just shoring everything up and getting some styling going on to finish it off
