ehm.. i use m6.03
from help:
/clearall [-snqmtgu]
Clears the buffers of the specified windows, where s = status, n = channel, q = query, m = message window, t = chat, g = finger, u = custom.
If no switches are specified all windows are cleared.
i use this to clear all when i change theme, but this only works for active server (so if i am on 2 or more it wont apply to others)... why ? and how to make it to apply for all server windows/connections ?
