I've installed Xoops with AMS, and this module appears to offer most things that I need (e.g. clean URLs for SEO). However, it is not possible to post the same article in multiple topics. I was hoping that anything posted in a subtopic would automatically appear in the parent, but this doesn't appear to be the case.

Is there any way round this issue, as it's vital for my site that I can quickly and easily post in multiple topics. I was hoping to find a solution through the Tags module, but haven't been able to do so. Does anyone have any suggestions?
