Hi Allen & Vipermad!
Yes, sorry, I had totally meant to post what version I had, but in my excitement I spaced it. Yes, Vipermad you listed it correctly. We're running 5.45c. Today my girlfriend's niece just installed your "Who's Online" hack. Which btw, works beautifully!!! But unfortunately that's the last hack she'll be able to do for us, since she's a full time University student & only home on winter break. We had to really beg to get her to even do this one. So my site partner (& best friend) was the one who suggested I look for a hack like this & see if it was easily doable for us or not. Sorry I'm not very technical & that I don't know what it would be called. Remember, we ourselves have never attempted messing around with ubb code. So we're talking absolute total newbies here. lol So please be gentle with us.
