Re-pick Member's Membergroup

[PokémonS]

SMF 2.0.7

Hi,

For example, there are 2 membergroup:

- "Newbie" for at least 0 posts.
- "Pro" for at least 100 posts.

As usual, if a member reach at least 100 posts, then membergroup changes to "Pro".
But, I want members can re-pick their membergroups. Even they reach 100 posts, but they can pick "Newbie" group again.

Is there a feature like that?

Thx.

No. Post count groups are post count groups.

Joinable groups are normal groups.

Neither of the two options can overlap.
