/**
 * <p>
 * Makes you, as guildmaster, assign a rank to a member of the guild.
 * Command syntax something like : <TT>guildassignrank <position> <guildmember></TT>
 * Where position is the index of the rank.</p>
 * <p>
 * A special version of this command is the command to remove a rank. For example:
 * <TT>guildassignrank none <guildmember></TT>. It removed the rank of the guildmember
 * leaving him or her guildrankless.</p>
 * <p>
 * I think, but I'm not sure, that the guildmember is required to be online in the game.</p>
