I have prety much always stuck to PSPupdates (PSPs or whatever it used to be). I have found it to be informative, friendly, honest, current, user friendly (very NB!) and mostly patroled by well meaning mods.
I'd say we're going through a bit of a bumpy ride at the moment. Maybe because of the preasures from the PSPAdvance episode. It has been supremely tough on the Mods. Supremely irritating for the members. But it is probably just a fase, and it will pass.
But what about other forums? Do they go through this as well. I joined a mobile forum a while back when I needed some help. 2 months went by and I still did not get a single respons to my question. That's my only other experience. What about others?
