You can create a custom sign up box for your Myspace page so that your new friends can sign up for your list with one click.
Then, your new friends will be automatically entered into your DIA Headquarters into a group you've created just for them. This way, you'll be able to see who's signing up through your Myspace account and easily contact them later.
Here's how to do it:
1. Go to your DIA headquarters and create a new group for your Myspace signups. Be sure to copy the group key, a number found at the end of your URL when viewing your new group. It will look something like this:
https://secure.democracyinaction.org/YOURSHORTNAME/hq/groups.jsp?groups_KEY=47223
So, in this case, you need to copy the 47223. We'll use it later.
2. Go to your Myspace account, and click " Edit profile"
Paste the code below into your " About me" section. Be sure to change all the placeholders with your org key, your Myspace URL, and your group key.
Hit save, and there you go!
Update: Yeah, not so useful in image form. Here's that stuff in copy-and-paste form, updated for Salsa:
<form method="post" action="http://salsa.democracyinaction.org/dia/rest/process.jsp">
<input type="hidden" name="table" value="supporter">
<input type="hidden" name="organization_KEY" value="YOUR ORG KEY">
<input type="hidden" name="redirect" value="YOUR MYSPACE URL">
Email Address <input name="Email">
<input type="hidden" name="link" value="groups">
<input type="hidden" name="linkKey" value="YOUR GROUP KEY">
<input type="Submit" value="signup">
</form>
