1. editing the resource strings would require switching to the DB localization provider. We will correct the typo in the new release. The general issue with the dialog messages is that they cannot be just exposed as properties, since there are localization issues involved (every message can be localized to unlimited number of languages, so it cannot just be a simple string property). The new release deals with it by allowing you to override the critical steps in the workflow, so there is some programmin required.
2. what info are you referring to?
3. again, this is stored in resource files (DefaultResources.Email_Activation_HtmlContent and DefaultResources.Email_Activation_PlainContent). We will enable users to override the default behavior of the mail sending process and enter anything they want.

The new release should be ready by the end of November.

I meant email info such as reply-to address, email account, uid, password, etc. I'm assuming it won't send confirmation emails to users until this info is entered somewhere?

Reply-to address can be set in web.config (or portal settings pane): "Mail from address".
All other information is pulled from the user profile automatically. The resource file values specify only the "static" mail message content and its format.

What sends the email out? Shouldn't there be somewhere I input my SMTP info at least?

Look at the web.config SMPT configuration section, and you will find it there - it is a standardized way of doing this.
MonoX takes care about plenty of such housekeeping tasks. Admittedly, it sometimes requires a bit of configuration to achieve what you want, but it has to be done that way to cover the largest percentage of possible scenarios.

So, to insert username and password data into the SMTP section do I just add a and ? Sorry to ask such dumb questions, but thank you so much for all of the help you've provided me thus far.

Thank you! Everything is working now.
