If you want to know whats happening that is general for all the guild then the new calendar could be helpful athttp://www.converttoraid.com/guild
Then what to make sure I see whats new is actually when i joined the guild I marked everything as read. Then everything after that is highlighted, where someone has done a new post. Easier to keep track if done daily. After I have read all that I consider interesting, I just mark the rest as read for the next time I check the forum.
In the beginning it is slightly information over load.
For general information what happening in the guild the Converted podcast is something to listen to. Would also recommend listen to CTR Town hall meetings as well.
The town hall meetings can be seen at https://www.youtube.com/user/TheRealPatKrane/featured
The converted old episodes can be seen at https://www.youtube.com/channel/UCvnvcm ... T2gpOznbHg
To keep track if something is happen with short notice would recommend on twitter follow @CtRGuild as well as @Converted_CTR.
There are a tone of other twitters that you can follow to get more information but the 2 above are the most important for a guild information point of view.
