Hi,
Welcome to UBBDev. Unfortunately, putting in features like this requires you to manually edit the UBB CGI/Pl files directly to incorporate these features. Most instructions are easy to follow but if you want to avoid manual hacking, many hacks have automatical hacking files which, when used with a code hacking program, can simplify/automate the 'hacking' process.
Currently there are two programs: MultiHack and SHW. SHW is available at
http://shw.coders-net.com and MultiHack is available at
http://www.multihack.com Support for these programs vary from hack to hack so it's up to you to look for a hack that suppors these programs.
Good luck!
