World of Warcraft
Call to Arms
CTA is an add-on (mod) for World of Warcraft that helps players create a group. CTA has several features that allow players to search for open groups, advertise group needs, and control which players
are allowed to join the group and more. CTA lets group leaders create a profile of their group. This profile includes a short description, the maximum size wanted, the minimum level of the players in the group and even a password to join. Group leaders can even set the class distribution of the group members. Players can also use CTA to search for these groups using various search criteria. When a suitable group is found, players can try to join the group. CTA will automatically check whether the player has the correct level and class needed by the group. Only a player that meets the requirements will be sent an invitation to join the group. If a player is on the group leader\'s ignore list, that player cannot see the leader\'s raid nor join it using CTA. Group leaders can also make the group private so other players cannot see the group on CTA.
