I use the ported wordpress ME module in my XOOPS installation. It IS multiuser already and works very well, except for one problem... when comments are on moderation, there is no notification sent to the author to approve. Comments do get posted if no moderation is set. Other than this, the blog works very well. Take a look HERE

I have contacted Nononubu about this and posted here, but I've had no replies re comment post problem. May be phppp could help on this? then the module is good to go
