I'm using Aweber for my auto-responder and have a particular problem explained below. However, I think it can also be thought of generically.
Aweber expects a name to be delivered for subscriptions. If you select the subscribe with name checkbox, and put name in the "name identifier" field, it successfully sends the username.
However, I want to send the person's actual name using the values of First_name and Last_name, which are found in wp_usermeta. I tried using %%first_name%% %%last_name%% but those got sent as literals.
Is there a way of sending any given field(s) from wp_usermeta?
I feel as though I'm close to solving this problem, but I haven't been able to get over the hump. An answer is definitely worth a beer (or two)!
