No it's not ready yet.

I think what I'm going to do regarding the html is just change < to &lt; otherwise I'd have to add error checking for every field.

Yes there would be template changes. As long as you've edited your templates using the template editor then you'll have a custom copy in the "local" directory and so when you install, the new ones will go in the main template directory and then you can cut/paste the changes.

The changes are in:

my_home.html
my_public_home.html
my_users.html

I think that's all
