FYI, for anyone wanting to use this to add author tags via Google+ here's how to do it:
In template memberaction_dropdown
after
HTML Code:
<div class="popupmenu memberaction<vb:if condition="$page_class"> {vb:raw page_class}</vb:if>">
add
HTML Code:
<vb:if condition="THIS_SCRIPT == 'showthread' AND $memberinfo['postcount'] == 1"><a rel="author" href="{vb:link member, {vb:raw memberinfo}}"></a></vb:if>
<vb:if condition="THIS_SCRIPT == 'vbcms' OR THIS_SCRIPT == 'entry'"><a rel="author" href="{vb:link member, {vb:raw memberinfo}}"></a></vb:if>
(the second if condition is not needed if you do not have suite)
In template memberinfo_block_social
add rel="me" to the google button link to make it:
HTML Code:
<a target ="blank" href="{vb:raw social.google}" rel="me">
Instruct your members to add their member profile to "Other Profiles" on their Google+ account.
