Hi,
I can help with the PM notification, but the avatar would require a plugin to work.
For the notification, follow these conditional rules:
HTML Code:
<if condition="$bbuserinfo[pmunread]">
You have a new message
<else />
You have no new messages
</if>
If you wish to use this with some style, try this:
In the template
navbar, find
HTML Code:
<if condition="$show['member']">
<td class="alt2" nowrap="nowrap">
<div class="smallfont">
<strong><phrase 1="$bbuserinfo[username]" 2="member.php?$session[sessionurl]u=$bbuserinfo[userid]">$vbphrase[welcome_x_link_y]</phrase></strong><br />
And replace this with
HTML Code:
<if condition="$show['member']">
<td <if condition="$bbuserinfo[pmunread]">style="background-color:yellow"<else />class="alt2"</if> nowrap="nowrap">
<div class="smallfont">
<strong><phrase 1="$bbuserinfo[username]" 2="member.php?$session[sessionurl]u=$bbuserinfo[userid]">$vbphrase[welcome_x_link_y]</phrase></strong><br />
This basically makes the background colour of the welcome box bright yellow if there is a new PM, but keeps it regular colour if not. Alter it as you see fit!
Hope this is what you were looking for.
