Reset a field every month using AutoActions?

Hi,

I am currently working on a new website where users will be able to request me to do a specific task for them - each user will be allowed to do a certain number of requests each month. So I'm thinking to have a CB field to hold this value, and each time a user requests something, I'll manually decrease it. That way I can also display that value in front-end.
That's the easy part. Now my question is, can I reset this field to its default value for all users at the beginning of every month? I'm suspecting this is something AutoActions can do... Correct?

Thanks.

Ok, I must admit, I haven't used AutoActions in a long time...
I need to initialize that value during registration first. So this would use an AutoAction also.
My trigger I guess would be OnAfterSaveRegistration. The action would be to set my field to 10. And I shouldn't need anything else as far as the initial value is concerned... Correct?

Edit: ok that part is working just fine...

There does not seem to be a trigger based on a date...
But maybe I could use the lastvisitDate field, compare that with the current date, and if the last visit was done the month before (or even before that), reset the field. If it was done during the current month, do nothing. What do you think of that option?

You'd need to use the Internal Users trigger, which fires the specific action on every user row. Next use a Field action and set the field value as needed. Now you need to trigger your action on a month by month basis using CRON. The URL for CRON can be found within CB Auto Actions > Parameters as "Internal Users URL" (right click and copy the address) or you can manually process every month if you don't want to use CRON.

Another option could be to act on the after login trigger to reset it on a user by user basis when they login. You'd probably need to do some date conditions on the last visit date or keep track of when they purchased tasks for you and compare against that date.

Ok thanks Krileon, I'll try the cron route... It's probably the best of the two.
