For anyone interested this is my "form link" for ignoring a user in the user profile:

<form action="profile.php" method="post">
<input type="hidden" name="securitytoken" value="{vb:raw bbuserinfo.securitytoken}">
<input type="hidden" name="do" value="addlist">
<input type="hidden" name="userlist" value="ignore">
<input type="hidden" name="u" value="{vb:raw prepared.userid}">
<a href="javascript://ignore user" onclick="this.parentNode.submit();">
<img src="{vb:stylevar imgdir_siteicons}/ignore.png" alt="{vb:rawphrase add_to_ignore_list}" class="inlineimg" /> {vb:rawphrase add_to_ignore_list}
</a>
</form>

I have it all strung out in one line. Similar form links could be made for other features.
