Just one other question re the deleting of posts.
Does this forum software offer the option to hide posts.
I'm a mod on another forum, and sometimes it's just the right thing to do when some folks properly transgress socially acceptable boundaries(racial/personal/etc)
With the hidden posts method, any potentially insulting comments are hidden from view, but not deleted.
There is a mark noted for that particular reply that it was removed, but can be reinstated if required.
With respect to such offensive material in threads, we move the thread to a moderators only 'bad thread dump'.
We never physically delete any material on this other site either, just move it out of view when common sense implies it's the correct thing to do.
While the allocated time for editing is inconsequential to me, I think(as a forum moderator) 4 hours is probably too long.
On the site where I am a mod(Ausphotography), we've found that the 1 hour leeway is ideal.
Gives folks plenty of time to review their posts, more than enough time for someone else to reply and highlight some issue too .. etc.
And of course if the member realises that an edit is needed beyond this time they simply notify a mod to assist.
Irrespective of all this .. it's just good to be back on NG
