I think it would be useful to consider that any member of the group, who has been inactive for at least 6 months (no message on the forum, no participation in the events or connection on discord) is removed from the members.
Then, I will say that thanks to the various updates of the game, this allows to renew activities and maintain a certain interest, especially for those who like me play regularly within this group.
The new players who join us are sometimes new arrivals on GTA5 and I find it very nice to redo a CM or elite runs.
So I think I will still be among you in 6 months, if the original spirit of this group remains what it is (including with new members) even though I will soon have a new baby (another daughter, in the end of January)
