So again:
How can I do to let some users edit 60 minutes their posts on some forum, but other groups to be able to edit undefinitelly their posts there.
What should be the settings? On vbulletin default and on this mod?

Possibly we do not understand.

In a forum you can have:
- groups that use the default (not selected in my addon)
- groups that use the new limit (selected in my addon)

all selected groups have the same time.

if you want this situation:

default time 15 min (default vBulletin options)

forum A:

group B time 60 min
group C unlimited

this isn't possible with this mod

Is there a way to assign this to a usergroup, and have it be available to all the forums without having to assign it to each individual forum?

Any issues with the latest 4.0.3 beta release?

at this time the addon does not have it, as they are the forum the primary variable

the code should be ok, it's in beta because the tests were done on local

Does it work on 4.2.0?

DItto...anyone try it yet?

It's working for me, on 4.2.0 PL3

Users can't edit their thread titles or prefixes, is it possible to make this happen with this mod?

I hope this mod will not work with VB 4.2
Please reply if it work with 4.2
or is there any similar mod?
