Allowing for repeat duplicate email addresses

[gwilliams]

I am using the 'signup success' page to refer clients to a payment facility. If they wish to use this more than once, can the message that says 'Error -that email address is already subscribed to this list!' be overridden, and then for it to be possible for that person to use the same process again without being rejected because his email is already in the system?

Sounds a bit unusual, but varying circumstances have led me along this track .

...following Bretts reply below - Thanks Brett, discoverd that, and have altered text above to reflect more accurately my query.

Hi,

Yes, just did this myself so it's fresh, look in List Settings, Custom HTML, Signup Error (button on top), now look at bottom of page, there you see all of the error text including 'Duplicate Email Error Message' where you can change the text.

Actually sounds like you might be asking something different, do you want to ALLOW Duplicates?  If so, not sure on that, perhaps there's a setting in LMP?  

Dean, what you say?

You can allow duplicates with the following addition to your signup form:

<input type=hidden name=allowdupes value=1>

Alternately, you can overwrite duplicates with the following:

<input type=hidden name=overwritedupes value=1>

Hi Dean,

Thanks, I didn't know about that, is there an Ignore Dupes too?  Just like in the LMInsert function?

The options are detailed on the signup form help page, at the following URL:
http://www.listmailpro.com/help/30.html

No, there is not an ignoredupes option for signup forms - but there should be.  It's on the list now.

I might phase these features out of the signup form and set them up as a List Setting so they cannot be used and abused by anyone using a simple form post.  One such problem could be someone who writes an auto signup script to flood your ListMail installation.  With the option "allowdupes" they wouldn't need to randomize the email address.  While DoS / floods are not difficult to do it is an extra step that could discourage it.

Since I put it that way, I'm not sure that having the options in the form is all that much more insecure.   Though, it could cause unexpected results if abused when using custom signup-xtra scripts, etc.

Thoughts ?

would it be possible to have a referral check to prevent flooding?

Thank you Dean - all so simple after all.
The 'allowdupes' in the list of 'variables' on the help page I could not relate to - being that I am not familiar with terminolgy (and even then I would not have realised how to include it in the html).

Next big obvious question then: Can LMP be instructed via the form to not log email addresses in the system, so that I would not have to try to bulk eliminate them?

Thanks
