Welcome to the new forum! Although the user experience differs from vBulletin, it's a much easier to use interface with great new features. Help Guides are available that walk you through creating/editing your Profile Photo (aka Avatar) and Cover Photo, and answer common questions about posting, embedding videos, inserting photos, and Private Messages. Big thanks to @Pokey for editing my drivel so these guides actually make sense 😉
I've started new threads in the Issues & Help forum to report post migration issues and to ask questions on how to use the forum not covered in the Help Guides. I've also created a thread in the General Sevens Discussion forum that resurfaces some of this information as well additional things you need to know. My suggestion is to start there, then visit the Help Guides and start posting.
I'll leave this announcement up for a couple of weeks to catch those who don't visit the forum that often.
