This is a feature i've seen in two other scripts (Ircap, X-Cript). If a person joins the channel you're in, the script logs his ip, so if he quits and after a few hours comes back with another nick, you're informed that:
#op-spanishare Sonic999(6FE4C2F6EA89BFB5ED4BA4BBEE87E7x) antes era Sonic999^ZzZzZ ------> Sonic999 used to be Sonic999^ZzZzZ
This thing is helpful to spot ppl who think it's funny to get another nick and get into my chan and then start asking n00bie questions to which they already know the answer (or to which we have already answered).
I've been cheking out Invision's options and couldn't find it. I also went to Dalnet #Invision , but noone ever answered during the hours i waited.. they all seemed to be away.
Thanks.
