I have an att reseller as my ISP, I just found I have access to newsfarm iad highwinds-media com

I haven’t used usenet much since about 2009 or so I do know about indexers and have a newsbin license from way back when.

So the q’s are who is providing news servers to att, am I safe using them (considering I have to use my real isp login to access them) and who is a good indexer and backup news service if it is safe?

EDIT: Also, how do I tell if there are any limits on my service, My ISP’s help chat person had no idea what usenet is, or that we had access to it.

Thanks!
