Hey delfinovc,

I am really sorry that delay of this reply,

May i know what is CRM as you mentioned at above?

And what kind of script you would like to include? Is it you would like to include this script during the subscribe dialog pop up?

please advise.

CRM is customer relationship management software

It has several possibility of scripts, one of which is:
<script type="text/javascript" src="https://d335luupugsy2.cloudfront.net/js/integration/stable/rd-js-integration.min.js"></script>
<script type="text/javascript">
RdIntegration.integrate('abcxyzb53a0c1fda4c68a82280e3bf52', 'form');
</script>
It can also be a form actions.

It seems to me that subscribe dialog pop up is a good option.

I am not really sure how is that going to work because the subscription popup is actually an ajax call and the form actually get's submitted to a controller. Not really sure how can the JS capture the form?

Anyway the form for the subscription is located at /components/com_easyblog/themes/wireframe/subscription/dialog.form.php . If you need to add your own custom codes, you may do so here
