Mike;
Any suggestions we receive here we will try and put in future releases. Sticky topics should be fairly easy to add; if you wanted to add it on your own via the source code, you could create a column in the threads table called "sticky" and add a "y" or "n" value to denote whether or not the thread is sticky. Then just alter the SQL statement which displays the thread, ordering by that column first (ORDER BY sticky). In fact, it's so easy I'll add it to the next version!
