Can you make a Preview post button and a spell check button? (Page 1 of 2)

Note that you do this at your own risk. I have tested this and found it to work. If you encounter problems, tell me about them so that I can correct them for other people

1. Open common/spell_config.php
2. Comment the line that says 
$Spell_Config['DB_Type'] = 'PHPBB'; 
and add a line that says 
$Spell_Config['DB_Type'] = 'PunBB';
3. Find
  if (isset($Spell_Config['DB_Type']) && $Spell_Config['DB_Type'] == 'MySQL') {
    include 'spell_MySQL.php';
  }

Add after
  if (isset($Spell_Config['DB_Type']) && $Spell_Config['DB_Type'] == 'PunBB') {

    require '../config.php';
    $Spell_Config["DB_Username"] = $db_username;
    $Spell_Config["DB_Password"] = $db_password;
    $Spell_Config["DB_Database"] = $db_name;
    $Spell_Config["DB_Host"] = $db_host;
    // This is used in some others, but it looks like this is unset in the file: odd
    $table_prefix = $db_prefix;

    include 'spell_MySQL.php';
  }
4. Change any other settings and save.
5. Upload all the files in the common & native_mysql directory to the forum/spelling directory
6. Go to http://www.yourwebsite.com/forum/spelling/spell_admin.php
7. Install any dictionaries you want.
8. Delete any file ending with .dic on the server (to free up disk space)
9. Delete the spell_admin.php file off the server.
10. Open up include/template/main.tpl (PunBB) and find
<pun_head>
Add after
<script language='javascript' src='spelling/spellmessage.js'></script>
11. Open up post.php and find
<p><input type="submit" name="submit" value="<?php echo $lang_common['Submit'] ?>" tabindex="<?php echo $cur_index++ ?>" accesskey="s" /><input type="submit" name="preview" value="<?php echo $lang_post['Preview'] ?>" tabindex="<?php echo $cur_index++ ?>" accesskey="p" /><a href="javascript:history.go(-1)"><?php echo $lang_common['Go back'] ?></a></p>
Replace it with
<p><input type="submit" name="submit" value="<?php echo $lang_common['Submit'] ?>" tabindex="<?php echo $cur_index++ ?>" accesskey="s" /><input type="submit" name="preview" value="<?php echo $lang_post['Preview'] ?>" tabindex="<?php echo $cur_index++ ?>" accesskey="p" /><input type="button" value="Spell Check" onclick="openspell();" /><a href="javascript:history.go(-1)"><?php echo $lang_common['Go back'] ?></a></p>
