This will require editing the forum posts directly in the database.  Do you have access (and skill) to manipulate your database using Enterprise Manager (or SQL Server Management Studio)?

You can also use the SQL module of your site.  You might try this to have a look at the records before deleting them (lists last posts in each thread after 1/1/09:

select*
from forum_posts fp, forum_threads ft
where fp.threadid = ft.threadid
and fp.postid = ft.lastpostedpostid
and fp.createddate >'2009-01-01'
order by ft.forumid, ft.threadid asc

And then I would use the forum's stored procedure for deleting the individual posts which can be called using the following format:

EXEC Forum_Post_Delete @PostID INT, @ModID INT, @Notes NVARCHAR(1024), @PortalID INT  

Which I am sure is clear as mud... but I suspect there will be some follow-up here to help you :)

Hi Scott,

Thanks for the post.

Currently, I do not have access to manipulate the database as I am only an administrator of this particular portal. I am assuming the Is there some other way I can solve this without having to get the dnn installation admin in involved?

Thanks,

Kelly
