Hi Kjell and other in this topic
This is about the *issue* I have been nagging about in some forums (the support forums) on the Swedish phpBB support board, right, Kjell ?

[Because I'm a typing idiot, and really don't want to appear as such on the board, despite I really am

].
As I have understood the situation : I have communicated with both Kjell and Marcus about it on the Swedish support site by PM's - and when you look at the issue, for practical implications obtaining almost the same result, I do not see the need for MODding here, as already and also mentioned above by Tom :
As I have understood the situation it is about getting the right balance on the board in the support forums between some users having a really bad habit of editing their questions with making notes in the starting posts of a topic, the question asked has been edited, and thereby creating condusion for other readers of the topic and on the other end of the scale leave some slack posting wise for typing idiots like me.
The decision so far by the Swedish suppport site has been to set the forumbased permissions for the support forums for the group registered users to edit own posts to : "No".
I think in practice the same result could be obtained the remove the annoying phenomen of suers editing own questions and at the same time take a bit conderation for typing idiots like me by setting the forum based permissions for the group registered users for the support forum to "Yes", and then limit the time span a user have avaialble for editing own posts on global level :
ACP => General (tab) => Post settings => Limit editing time: Limits the time available to edit a new post. Setting the value to 0 disables this behaviour. (Which I suppose is set to zero minutes right now) By setting it to a suiable number of minutes , perhaps based on some trial and error over time, perhaps starting with 15 minutes or something like that, I think the wanted (from a pratical point of view, but totally Kjell's request, I know) would be obtained, without anything about the users behavior in any forums beeing regulated in a way that for any user seems too harsh.
If you really want to do it strict [your explantion is quite clear to me, Kjell

], I think it a quite complated matter, because it does not fit into the whole system and idea of the permission system ion a detailed level, because all persmissions setting that are not structured so that they are on local level (forum based level) can be phrased a setting like YES - NO or NEVER, has to be a global setting, bacause it to some extent be in conflict with the existing permission setting on local level :
"Can edit own posts"
to have a separate permission called :
"Can edit own last post in topics, when there is still no reply".
