[ask] Promoting Old Post

Do you know any plugins to renew post date so I can move old post to the first page in automatically?

I have been try OPP (Old Post Promoter) but it's only works 1 time only after 1 post re-update date then freezing (i don't know why, setting every 12 hours). I tried in 2 different blogs.

Right know I use STT2, but STT2 only promoting page with low visitor, so I got bad article all in front.

Any other choice? Please advise.

Thanks.

I think nobody knows or nothing plugins like that.
