Only future events get notified

I've done a few mods to the notify module. Through the help of various patches, I've rigged my version to:
1) allow the admin to select what content types are included in the notifications (so you can limit which node types are included) and also
2) include nodes that are edited to be included in the email
3) give the admin a button to apply the settings to all existing users.

I've attached it here. From what I've gathered on the support board, the owner didn't want to go this route with this module (fair enough).

So what I use my module is to restrict the notifications to only include event nodes. I still need it to do two more things:
1) include the start time of the event in the email
2) only include future events.

My plan is to set the interval to a week and users will get an email once a week with all new and edited UPCOMING events.

Can anyone help getting my modified version to do this? It'd be greatly appreciated.

PS - why don't I use the subscriptions module to do this (which was one of the questions of the notify module's creater)? I use the subscriptions module for DAILY updated of other types of content. I wanted a separate email to highlight events only.
