When you talk on a channel without using the ';' command, the mud has to search through all available channels to see which one you meant. If there is more than one that starts with the name you specified, then the mud reports an ambiguity. However, if the smartresolve option is set, then the search is restricted to those channels that you talked on most recently. The result is that the mud doesn't complain nearly as much about which channel you want to talk on. See also: channels
