Great, it works. Thanks so much

For anyone else interested this is the final code (obviously alter the forumid to your needs)

PHP Code:

<form method="post" action="inlinemod.php?do=domovethread&amp;threadids=$thread[threadid]">
<input type="hidden" name="s" value="$session[sessionhash]" />
<input type="hidden" name="securitytoken" value="$bbuserinfo[securitytoken]" />
<input type="hidden" name="destforumid" value="225">
<input type="hidden" name="threadids" value="$thread[threadid]">
<input type="hidden" name="do" value="domovethreads">
<input type="submit" value="Submit">
</form> 


Edited to add:

Another little update, the method above will leave a permanant redirect. I didn't want any redirect so I added an input to handle that:

PHP Code:

<form method="post" action="inlinemod.php?do=domovethread&amp;threadids=$thread[threadid]">
<input type="hidden" name="s" value="$session[sessionhash]" />
<input type="hidden" name="securitytoken" value="$bbuserinfo[securitytoken]" />
<input type="hidden" name="destforumid" value="225">
<input type="hidden" name="threadids" value="$thread[threadid]">
<input type="hidden" name="do" value="domovethreads">
<input type="hidden" name="redirect" value="none" id="rb_redirect_none" checked="checked" />
<input type="submit" value="Move thread to X">
</form> 


I found the code in the 'threadadmin_movethread' again so if anyone is looking for different redirect options, look there.
