This extension allows you to display certain members giving their ids as parameter's variable value.
I hope this extension will help to increase merchantability of your site.
Downloads:
For version 2.2.1 and 2.3.1
Based on new members extension.
Place .php file at extensions folder and .tpl at your templates folder.

Call extension in v.2.2.1 {promoted_members:} in v.2.3.1 {promo_members:}

You can look at the source code of .php to view all possible parameters but main is:
promo_member_ids

Example: {promo_members:promo_member_ids="2|14|21|17|65|777"}

Now you can charge your members for displaying them at the main page of your site.

I realize that it would be much better if someday we can use kind of table with user_ids and time intervals but we may ask it as a feature request in appropriate forum.
