I have it added here
<a href="post.asp?method=Topic&FORUM_ID=<% =Request.QueryString("FORUM_ID") %>&CAT_ID=<% =Request.QueryString("CAT_ID") %>&Forum_Title=<% =ChkString(Request.QueryString("FORUM_Title"),"urlpath") %>"><img src="icon_folder_new_topic.gif" height=15 width=15 border=0></a> <a href="post.asp?method=Topic&FORUM_ID=<% =Request.QueryString("FORUM_ID") %>&CAT_ID=<% =Request.QueryString("CAT_ID") %>&Forum_Title=<% =ChkString(Request.QueryString("FORUM_Title"),"urlpath") %>">New Topic</a>
In my topic.asp that's line 848 though I have a number of mods so it may/will be different for you. Look for the phrase NEW TOPIC and you should fine the line I posted above.
