Can we delete all posts by "guests" in one hit?

Hi,
Can we delete all posts by "Guests" (deleted users) in one hit?
Forum has been in active for yrs as life got too busy, Wouldn't mind trying to get it up and running again but all post by Guests doesn't look good

There is not a default way.

Bugger!!
Not sure how else too do it as all members had been deleted so every post but mine are from old members

what you could do is do a backup of all your members if you have not long deleted the accounts and then you can use this system.

Their accounts were deleted yrs ago i think as i was closing the forum down but then decided to leave it as there were things i wanted to keep.
So i guess that wont work above?

Since im the only member how do i back me.up??

Back me.up?

Ok,
If I did it correctly it didnt work, Looks like i will have a LONG job ahead of me

You do know that you can use the moderate link which loads a new page that you can check the boxes then click delete.

Nooooo but that would save alot of time also!
Thanks will jump on comp and have a look at how to do that

is this now solved ? if yes please hit the big green Solved button and post solved so we can lock this

Thank you.

It sure is!
The forum looks so clean now without all the "guest" posts
