Lucky Teams is a lightweight teams plugin, made for simple factions like gameplay. Since this is a bare bones version, there aren't any features apart from creating, joining and leaving teams, but many of my upcoming plugins will have some sort of LuckyTeams-Integration, for example: You can activate LuckyTeams support in my LuckyHomes plugin to make team homes possible.

Features:
As stated, there aren't many features in the standalone version, but there are some. These include:

• Creating teams
• Inviting players to your team
• Kicking players from your team
• Leaving teams
• Updating the team name, color, item and Joining-Behaviour
• Displaying the teamname above a players head and in chat
• Joining, Requesting to join
• As of the 1.3 Update, There is also a GUI

Usage:
The plugin relys on the tab completetion of minecraft to make it easy to use, here's a rundown of the commands should you have problems with them anyway:

" /team" open the GUI

"/team create <teamName> <color>" creates a team with the name <teamName> and the displaycolor <color>

"/team join <teamName>" tries to join the specified team

"/team invite <player>" invites the specified player to your team

"/team accept <teamName>" accepts the invite of a team

"/team requests list" lists all join requests to your team

"/team requests accept <index>" accepts the specified request

"/team requests remove <index>" removes the specified request

"/team kick <player>" kicks the specified player from your team

"/team leave" leaves the team you're in

"/team set name <teamName>" updates your team's name to < teamName >

"/team set color <color>" updates your team's displaycolor to <color> (NOTE: the plugin only accepts the spigot CHATCOLOR-names)

"/team set item" set's your team's GUI-icon to the item you're holding

" /team set entry <entry-policy>" set's your teams joingin-behaviour
(all - request - invite)

Possible Problems:
My plugin adds a tagline with the name of the team infront of the player name. This is done through the scoreboard of minecraft, so it could cause problems if you have any other plugins that change something about the playername installed.

Planned features:
lang-file
more customization
