When you are in the wiki starting page, there is a 'BROWSE ALL WIKIS' button you can press and it supposes to show all of the wiki entries in one page, but the link is wrong. It points to ".../wiki/alpha/a" currently but the right link should be "/wiki/alpha/all".
The other problem, which I am not sure whether if it is a bug in the WYSIWYG editor or not, is that when you go to another page to copy some text then return to paste it in the editor, the flashing cursor (typing indicator?) will disappear. You will have no idea where your are typing. The simple fix right now is to move the mouse cursor to the title box, click on it and it will show the typing cursor again, then click on the message box so the typing indicator will show again.
