Hey man, thanks for the invite - it totally expired though since I haven't been active on DA for the past few weeks. Sorry about that! I'd love to be one of the first members of your group.
Hi! No worries at all, I know sometimes the invites for groups and gallery requests can time out. Great to have you join us though honestly, I love your artworks a ton and it's an honor for you to share them with the group here!
