[Plugin: BuddyStream] Fake download

is just one Kb .php file, not a real plugin. On their website, they ask for donations so they can release the plugin (need funding :)), so I guess the question that you should ask yourself is: they (he/she/whoever) will ever release this or is just a cheap scam?!?
Myself, I’m not going to donate for…nothing – maybe after I’ll have the plugin and I’ll decide is usefull, that’s how donations should work, I think. Besides, cannot even register on the site to test the plugin live.
