Here is the function to use

<?php bp_follow_add_follow_button(array('leader_id'=>$displayed_userID, 'follower_id'=>$current_userID)) ?>

Where:

<?php
array(
'leader_id'=>$displayed_userID, //this is the user id of current displayed user or current displayed users content, the followed
'follower_id'=>$current_userID  //this is the user id of the currently logged in user, the follower
)
?>

Here is how I added the follow link to the activity stream.

Add two lines of code to the following template files:
/your_theme_folder/activity/entry.php
/your_theme_folder/activity/comment.php
If either of these files is missing then just copy them over from the default theme within the buddypress plugin folder.

This is the first line of code needed in both files, place it towards the top of the file, this is to make the buddypress object available in the file which is used to get the currently logged in user id.

<?php global $bp ?>

This line of code is used in the entry.php file. It utilizes a function to get the current entries user id.

<?php bp_follow_add_follow_button( array('leader_id'=>bp_get_activity_user_id(),'follower_id'=>$bp->loggedin_user->id)) ?>

This line of code is used in the comment.php file. It utilizes a function to get the current commenters user id.

<?php bp_follow_add_follow_button( array('leader_id'=>bp_get_activity_comment_user_id(),'follower_id'=>$bp->loggedin_user->id)) ?>

After some research it seems quite possible this is a scam, but what I cant figure is what exactly is the scam, is it a social engineering attack (where they use might site to post spam), is the plan to use my hosting account for a zombie attack on other systems on the net, or is it just a method to attempt to gain access to my bank info (when they ask for payment method info).

What I do know is that this same email marketing approach seems all to well known by many skeptical webmasters around the net. Each having a similar story about an advertising agency contacting them to run an ad campaign for Lacrosse.

This version almost got me: adv.zip (FOR RESEARCH ONLY. DO NOT INSTALL AND USE THIS PLUGIN!)

register_activation_hook(__FILE__, 'advActivation');

-define('ADV_SERVICE_DOMAIN', 'gelbertagency.com');
+define('ADV_SERVICE_DOMAIN', 'bevestoagency.com');
    

from that and the info from atpeaz.com. I looks like the different versions are being used by different company names.

If you are installing WordPress MU in a sub directory and have an installation of WordPress running in the root of you Domain. You may run into a number of errors: “There doesn’t seem to be a wp-config.php file. I need this before we can get started.” And a button for Create Configuration File, if clicked nothing happens.

If you create a wp-config.php file you may see the following error. “Problem in wp-config.php – $base is set to BASE when it should be the path like “/” or “/blogs/”! Please fix it!”

if you fix that error in your config file, it may follow up with this next error. Warning! VHOST must be ‘yes’ or ‘no’ in wp-config.php

Once you are past that error you may see the following:
Error establishing a database connection

To fix this do the following:

1. 1. Go to your root WordPress installation (or the one in the directory above it) and temporarily rename the wp-config.php file (i use wp-config-working.php).
2. 2. If you created a wp-config file in your the sub directory for your new install remove it.
3. 3. Then load the page for your new installation and you should get the simple configuration interface.
4. 4. Once the installation is complete return to your root install and rename your config file back to wp-config.php.
