Invitations to closed foreign trackers of the training subject (Part II)

"Knowledge is power". Francis Bacon.
"May the Force be with you." Obi-Wan Kenobi

So, the captain once again reminds me that on the calendar is September 1st. He also informs me that today, in many CIS countries, Knowledge Day is celebrated. And I propose to continue the good tradition of extending access to high-quality educational material, which is located on closed trackers of educational topics.
This year I myself became a student again and will study in Frankfurt, Germany.
In honor of the Day of Knowledge, I do a holiday distribution of invites to foreign trackers. And also I invite to participate in this distribution of habrapovayruzha with invayta. You can get an idea about trackers from the article - Overview of e-Learning trackers or Live and learn! and its second part . Materials on all trackers mostly in English.
Who cares - welcome under cat.

There are invitations to BitSpyder ( 9 ), eBookVortex (5, you can register without an invite), MyAnonaMouse (5), docspedia.org (1) .
Write in the comments to the article on which tracker an invite is required, only who really needs (and not to) was sent to habraposhta. According to the experience of the last distribution - a third of those invited from Habr to BitSpyder were banned for a low rating. Therefore, I ask you to take this seriously and with understanding. At BitSpyder, requests from people with karma are accepted> = 5.

UPD:
On BitSpyder, invites are over. All unsubscribing will issue as I have new invites.
UPD2:
An invite has already been issued to docspedia.
