Hi guys,

I'd like to know how to set-up (or what plugin) I can use for customized opt-in forms?

Right now, I have several Aweber web forms on my site.

1. Specific ones for my sidebar (with free ebook),
2. for my about page (no freebie download),
3. pop-up (lightbox, with free ebook),
4. and one at the bottom of each post (no freebies)

My problem is, I want to offer a special opt-in for just one particular post I'll be having next week.

That post is a tutorial by a guest blogger, but I want a special opt-in form so I can send a discount code to those who'll sign-up to this guest blogger's workshop.

Since I already inserted the #4 item above, the aweber code into my single.php (bottom post), how can I override that old code from showing up and just have the new opt-in show up?

Thanks in advance.

Hard code or plug-in would be fine.
