This is what I did as a test for it (NO HACKING OR ALTERING THE INDEX.PHP):

In ADMIN CP do this:

1. Templates ->edit

2. Defaults ->[expands list]

3. Forum Home Page Templates ->[expand]

4. forumhome_welcometext ->[edit]

5. Change 'Welcome back,' to 'Hello,' Without the ' '
It looks like this: Hello, <b>$username</b>

6. and then copy and paste this: | <smallfont><a href="member.php?s=$session[sessionhash]&action=logout">Log Out</a>

It should now look like this: Hello, <b>$username</b> | <smallfont><a href="member.php?s=$session[sessionhash]&action=logout">Log Out</a>


7. Save Changes and check out your work
