Changing the last post ID?

[DislexiK]

Good day all,

While testing something on vBulletin I created around 50 posts, I deleted these posts which is good however is it possible to make the latest post ID go to 400 instead of 450, it is a weird request, however I like everything neat and would like to go make it as if those 50 posts were not made.

No other posts have been made since the 50 test posts so nothing should be damaged changing this?

Thanks for your time.
