It’s amazing to me how many folks change guilds without doing the easiest, and possibly the most essential pre-guilding step: visiting their potential new guild's website. Hell, I have been in multiple guilds where the bulk of the members never registered with the website, or they visited it once to app and never went back. Don’t be that person!!
A quick trip to the guild website is a must for a variety of reasons:
1. It will have their events calendar and raiding schedule, and often their progression notes.
2. If it is a raiding guild, it will usually have their DKP rules or loot policy.
3. The posts viewable to the public will give you an overview of how the guild wants to portray itself to the server at large. If the site is raunchy and notes that having a good sense of humor is important, and you’re offended just reading their application, it’s probably not going to work out.
