As lot's of forums we have a classified section.
But it's a pain to maintain since the users are not able to delete and modify their ads.
(We have to restrict this on our main forums)
Are there any plans to make delete/edit configurable at forum basis?

We have considered PhotoPost Classifieds, this integrates with the IPB user database.
Anyone who have experience with Photopost?

Are there other alternatives?

Photopost is coded to work with Vbulletin. I think this would be good as another addon like the blogs and or gallery.

From their page:
If you already have a forum (vBulletin, UBB Threads, phpBB, DCForum, or InvisionBoard), you'll appreciate that PhotoPost Classifieds was designed to seamlessly integrate into your site without the need for your users to register twice and maintain two logins.

Yes but it dose not give you the option of using your forum skin for IPB or any other forum script EXCEPT vB

Login and CSS is integrated.
vB Enhanced integration is the ability to have the header footer pulled around our product as well as post icons smilies etc. This shouldt be too difficult to overcome.

Few references to IPB over at Photopost,....
As far as I can tell there is no link between Photopost and the IBP user profile, sending PM directly to a poster is not possible.

well when you are using a script coded for vB on an IPB its going to get fun1

Yes, but as far as I can tell there is no alternative to Photopost at the moment.
We have to to something, I'm tired of request for ads removal, change of price etc.......

mybe IPB will pick it up and start production on something like this

Yes please....
As far as I have seen, almost every forum have some sort of classifieds section so there must be a market for this.
(Photopost cost $99)
