I added the widget through the widget page within wordpress, but had that comment in there as a placeholder to make sure I knew where it was going after I placed it there via the admin widget page (hope that makes sense) ;)
Thanks for the info on the HTML warnings, I'll definitely look into it and see if I can clean it up!
Some more background info that is probably helpful... I had purchased "Subscribe2" about a year ago, and it was working just fine as the widget. Then in November I got the notice you were moving to a different vendor for subscriptions, and got the cancellation notice via PayPal. That's also the time when I realized the text box was no longer showing. So I deleted the "Subscribe2" plugin completely, and re-bought the "Subscribe2 HTML" plugin from SemperPlugins, and installed that, thinking it was my license that had expired, causing the form not to appear.
Could that be the issue? That I screwed something up when I removed the old Subscribe2 plugin and replaced it with the Subscribe2_HTML one?
