So I deleted everything and started over. Its working now but I still ran into a few problems. 

So you need to log in in order to add a comment. When I log in I still get an error writing data. 

Auth: success

Not really sure why I get this error. The user www should have full access to everything. However I suspect
an issue with one of the files /bin/umask does not exist in plan9. So I did a grep to search for it
I found it in two areas. 

/usr/www/werc/apps/bridge/app.rc:88. I would comment it out
I also belive app.rc:91 is incorrect
I think app.rc:91 should be
mkdir -p $dir &&

Auth: success
sites/cirno/_werc/comments/1642460857/user: ./apps/bridge/app.rc:93: can't open: 'sites/cirno/_werc/comments' does not exist

I still got another error. I guess you need to create the directory 'comments' in sites/cirno/_werc/

so I had to manually run
mkdir -p comments while in sites/cirno/_werc/ directory and then run
chmod 777 comments

Not exactly happy about that but it works. 

Wiki is also another issue and required the following

mkdir -p sites/cirno/index.md_werc
chmod 777 index.md_werc
chmod 777 index.md

I also had to remove umask from apps/dirdir/app.rc

So two directories are 777 and one file. But now my other plan9 users can make changes not that I have
any users but this is kind of bad.
