I have started to feel other members may use and hang around on some other forums or sites too. For me this is the only forum and site I use. I could like to check some good linux, hackr/cybersecurity, retrogames, scientific (watched a lot ted talks with iphone but since I can't play youtube vids straight with N900...) or conspiracy sites or forums.

If you have knowledge and you like to share it - please, be my guest.

With pc I watched a lot of stuff from Top Documentaries site. Have also checked some stuff from Forbidden Archeology (have to filter a lot though) etc. Searched a lot info about civilisations and their ruins which doesn't fit in the accepted and official history writing and chronology.

Also have liked to watch defcon and blachat conference lectures. But I don't know any good forums besides this one.

You might check media.ccc.de for the recordings done on Chaos Computer Club events and many others where the CCC "Video operations center" did streams.
Most content is in english.

Other forums? Blasphemy

And if you just want to know something from the 36th chaos communication congress (this is a sub of https://media.ccc.de) you can try Congress at openrepos or harbour (now with offline video support).

Just trying to find something I could make use of with my N900. That one I can't.

To the hidden question in my hint:
Does media.ccc.de open correctly on your n900?

No, it doesn't. And even it does I can't watch any vids with N900. Or can I? if you can.- please tell me how?
