This addon basically filters all status messages sent by Guild Event Manager 3.

I was annoyed of the resource usage of GEM3 because my raid just uses it to join a channel. Because of its status messaged its nearly impossible to join the channel for chat and read the chat without seing all those GEM-status Messages with cryptic information.

+ Very low Mem and CPU Usage

- GEM Traffic is still there, it is just not shown anymore

Warning: This addon only blocks GEM3 status messages, GEM2 messages will still be shown
Since 0.2 the Addon will only initialize and filter if GEM3 is not found running.
Since 0.3 GEMFilter can autojoin channels for you. Type /gemfilter to see how this is configured.
Since 0.4 Itemlinks will work if the channel is configured in GEMFilter.
