AkoForm Email bug / patch availability

I've got AkoForms posting fine, and it generates an email to a site admin.

In the form, the user enters an email address, and in the generated email, the address comes through with a "! " inserted within the email address. But the email address saves to the database just fine.

2 questions -
- how to eliminate the "! " from the generated email
- how to get an update to AkoForms (or even know when one is available)

Thanks.
