Are you talking about OSRS Group Ironman? If so, you are in the wrong forum. Have you tried LFG in game or in the OSRS Forum? Do you know you start from scratch with GIM in OSRS so your levels are irrelevant so nobody really care about a group now.
If you are talking about RS3, there is already lootshare for ironman group for a long time. No need to wait weeks and then start from scratch. Perhaps you can just hop to lootshare worlds and get your group right now.
