Members and bbPress

User Role Editor and Members are fundamentally different. URE is used to manage the capabilities of users and roles (create new roles..etc), while Members plugin manages which roles can see which posts.

Any roles you do create with URE will be usable with Members plugin and the extension I wrote. The new roles will appear in Content Permissions when creating new forums. Check the roles you want to have access to the forum, and thats it.

Sure, should be fairly simple to implement. I have to an update to have it support filtering the BuddyPress activity stream, I will use that time to look at implementing filtering for topics as well.

Subscribe to this topic or my site. I will post once I update the plugin. The update should be done sometime next week.

If enough people are interested, I might make this an actual plugin on WordPress downloads.

I started looking at it. Yesterday I released an update that fixed the issue with BuddyPress and activity feed. That was higher priority since it showed the actual post content vs just the title.

I had to reinstall my PC so I lost a lot of time. I am hoping to release the topic filtering soon.

Subscribe to my site (email or rss) as I will be posting updates through there. Once I implement all the necessary filtering and make it so that it is not dependent on Members plugin I will be releasing it to WordPress plugin repository.

Sorry for late reply, I get to work on this only during my free time.

Thanks for pointing me to that file. I looked at it so many times and missed that code every time. I think I have it working now. I will be releasing an update once I clean things up a bit.

I tested the commenting system on my site and it is working fine for me. Did you get any errors?

Here is the code I used. I could not encounter any issues, but then again my test forums are somewhat small.
