Based on smf2 (i sure its the same in smf1 but i never usd it)
Allow grants the permission based on a membergroup
Disallow does not grant the permission
* If however a user is in a group that allows the permission and also in a group that disallows the permission, the permission will be granted via the group that allows it.
If a permission is denied to a group the user is in the permission will be explicitly not granted even if the user is in another group that allows the permission
Thanks for your reply, and I read it several times before I was sure I understood it. I do understand what you are saying, but you also said "Based on smf2 ..."
I looked at the permissions (I've looked at them and set them for years but looked again) and I do not see "allow" "disallow" and "deny" in the permissions or any implication that they act like you are describing. All I see is a check box that is either checked or not checked for the permissions. Is there some underlying scheme I've never understood all these years that I need to be aware of, or are we just talking on two completely different levels (me being on the lowest level I'd guess :)).
Thanks.
