WordPress and ChamberMaster
 

Has anyone built a WordPress site that integrates with ChamberMaster modules? I'm not familiar with ChamberMaster but may migrate an existing site to WP and I'm wondering if I should leave parts of it in CM or scrap it entirely. (I hope this makes sense)

That appears to be more or less standalone not something integrated with WordPress. I've never worked with it but it would probably be a pretty big job to integrate it.

That's what I was afraid of. Hopefully I can get them to move away from it. I think the reason they use it is so that Chamber of Commerce members can edit their own listings. Is there an easy way to do this in WP or do you need to make everyone a user? Can you limit them to their own page(s)?

you can make members "authors" and then they can edit their own listings. There are also several membership plugins that would work for this type of usage.
