Account Switch Option

I was not really sure where to post this topic. If it not suitable to be here, please move it someplace else.

Since I was able to restore one of my oldest forums, I think it is time to do some work on it. And the very first thing that I need to be created/done is to allow the option ot members to switch between their accounts. (The forum is a RPG one and this option is highly essential as the members have more than once account.)

I found the following topic which I think is helpful...
