My UA file in the webassist/email folder is named waue_landing_3.php because it is the third one created for the page.
The attachment was changed to a txt extension so that it could be uploaded.
Of course the user inputted content will not appear in this template file, but the body text that you add will. This is the only place it will appear.
Yes, my server displays .php just fine thank you.
Do you work with WebAssist, or are you just trying to be helpful?
