G'day Tibsie,
Thanks for posting your interest in SA. If you haven't done so already, have a read over the following recruitment posts in this forum to get an idea of what SA is all about, what we are looking for, and the process for getting guilded with SA.

Then it's probably best to try and catch up with people online and try and chat / group etc to find out more about SA from our members. If you like what you see / hear, then ultimately, you'll need to have a chat with our guild leader Zelin to progress from there.
I see Zel has replied to your post, so hopefully that answers some of your questions. The posts I linked above may also help there too. Otherwise, feel free to catch any SA members online if you have any further questions, or post here if you are stuck at work in the meantime.
