I'll change it in next version. 

I dont know why we cant create admin based AS that have on specific forums when it appears I can create them as a user.

A pity as being able to select the subforums for the activity stream is a must for some communities. But while this is in revision, I have to say that the capacity of excluding subforums (rather than adding them in) would be even better, particularly when you consider some communities have many subforums and only a few of these are generally the ones people need to leave out. That's the way it's been in previous versions of IPB when it came to New Content too.

Please explain this.

Verified with a ticket that it's not something that can be returned at this time, but believes it is being talked internally so should be added soon. 
 
Hopefully sooner than later, that was one of the things that we've been "living without" for a while now, but would love to have it back.

When I went to your link I saw no error. but what I do see is the login screen to the upgrader.
I'd throw you a screen shot but I am still reinstalling all applications after a system melt down.
So give it another try is all I can give at the moment
