post count doesnt change when posts deleted... questions

[sammy22]

i ran a query to raise post count up, the reason i did so was that i deleted posts before i knew that that would lower the post count (DUH) anyway....

if i use this hack(prune does not lower post count), then run the database query to raise the post count back to where it was before i pruned, will it make it more perminent?

for some reason every once in a while, the posts go back down, and i have to run the query again. i dont want my members wondering why the poast count is going up and down so much.. thanks
