Moving Digsby installation is kind of tricky, you have to locate and copy to new machine these two folders: 1, digsby folder with it's settings and cached files, without it, digsby will not work for you 100% correctly (ex. you'll loose your contact's avatars and they will be refreshed only when they change it). I found this folder in c:\Users\s\AppData\Local\Digsby\ on my Windows 7 machine, where "s" is my user name. 2, if you care about your chat logs (I certainly do), copy also this folder: c:\Users\s\Documents\Digsby Logs\ shame that no portable Digsby edition exists... Have fun and speak your mind in digsby's forums for portable edition :)
