<-- profile box there with vb 2.3 and 2.3.2 there was a mod/hack to have it appear to tell you if that person was either on the forums or not, in the form off 2 two words online or offline.
If you look right under your post, you will see some buttons. See the one that says "profile"? Directly left of it is an image that will show if someone is online or offline. There are two templates controlling this. One for online, one for offline. So you edit to that, and then remove it from postibit, and place it where you want it.
Just use simple XHTML text to use wording for online and offline using the same variables. And move the variable in your postbit template. If you need further help, just say so.
