You may think 'I cba to check a separate forum. We have the guild chat to communicate, so why do I need to browse a forum where i have all the hassle of registration and searching topics?'
The reason why we recommend that you do it anyway is that our guild is growing and it will most likely happen, that members will be online at very different times. You might get guild mates you never going to meet ingame, because they can't play when you are playing.
Yet there may be some days (i.e. weekends or holidays) when you play at the very same hours.
Having never met these guild mates makes it most unlikely that you recognize eachother as friends which you are supposed to be as mates.
If you communicated with eachother on the guild forum before, you will know your mates and be able to play together as friends, acting as a guild.
You are part of a community, a growing community. Do yourself a favor by integrating and helping others to integrate.
Don't look at people you never met as someone you don't need to care about. It's been the spirit of Resonance from the day of foundation that people we don't know yet arefriends until they prove that assumption false. The pure fact that someone joined the same guild as you, should tell you that they want to become your fellow. Don't push them back but welcome them and try to get to know them better.
There is no better way to accomplish that than having a place where you can meet without the restrictions of individually available time.
