I used the user_options abstraction in WordPress so that it should work for the multiuser case.

At the moment, the maximum reminder length you can set is 7 days using the admin, to change this you have to hack the plugin and increment the maximum in the for loop in action_personal_options. I will probably up this maximum to something longer like 14days in the next version, 7 was a quick punt for a sensible maximum. I will also add a filter on this value to enable you to modify this maximum without hacking the plugin in future.

As for setting a default, the plugin gets it’s default of 0 from the way the filter on get_user_option_pjw_blogminder_threshold works. It filters the value and ensures it is a positive integer. If no value exists the value it gets to filter is false and absint makes this 0.

The best way for you to filter and set a different default is to add a second higher priority filter on get_user_option_pjw_blogminder_threshold which returns your default value if it receives false.

I’ll look into adding a filter for default value in the next version too.

I am trying to get this to work with wordpress MU.
Is there a way to have a default value set when you install the plugin? Say I want a user to be reminded every 14 days but without going to the profile page and setting it up himself.
So basicly I am asking where in the code I would have to edit to make the default “No reminder” to be “14 days” when installing the plugin.
