In relation to the thread, what is your point? I'm not sure what sort of rational (or irrational) thinking you went through to come up with the solution that you did, and now you're arguing in an attempt to suggest it's all simple with no nonsense. Would you please explain what makes you so sure this problem is related to multi-user configuration?
I see multiple instances of a single-user configuration in a multi-user environment to be extremely complicated by comparison to a single instance of a multi-user configuration that saves everything to the correct places. Do you also explain how to set privileges correctly for underprivileged users, so that the admin can expect basic changes such as nickname and colour themes to be saved after mIRC is closed? If not, how do you counter this problem?
