I can't make a comment on a friends post. The option to comment  is not even avalible.

When someone who is a friend makes a jounal post. I should be able comment on it.

I looked for a setting in the control panel for comments and didn't see anything.

By default, comment permissions are set to "Only Me". This is unintended and will be fixed. In the mean time, you can login as that user and go to My Settings > Journal Features > Add Comments

is there a way to do a SQL script to make all settings to "friends" if it's currently set to Omly Me? if so, what would the script be to do this. I have been invited to signup close to 2,100 users this weekend and will need to make sure this is set to "firends".

You could use a script like this to set all users comment permissions to "Friends Only"

Not sure how to setup a schedule. Is there a way to have this script to run every _____ minutes? If so, please give step by step instructions on how to set it up. Thanks
