Hello !

This is how you can make a nicer button for chat and make it appear only when the seller have a account

Here is a example of annonce without the seller registred : https://www.lannonce.eu/electronique-et-electromenager/telephonie/telephonie-dans-bruxelles_i1257

And here a registred seller : https://www.lannonce.eu/vehicules/auto/auto-dans-aix-sur-cloix_i1214



And the code is :
<?php if(osc_item_user_id() <> 0 and osc_item_user_id() <> '') { ?>
                <?php if(function_exists('im_contact_button')) { im_contact_button(); } ?>
              <?php } ?>

MB-Themes plugin is the best, you can buy it from here :http://mb-themes.com/osclass-plugins/32-osclass-instant-messenger-plugin.html

Hello, if you use the last version of instant messenger and if you want to replace contact button you don't have to use this anymore.
Thanks
