There is a very helpful Blackboard Wiki that addresses many questions and answers about Blackboard, such as

• I can't see my course on Blackboard - what can I do? 
• Students can't see my course on Blackboard - what can I do? 
• How do external sutdents get access to my Blackboard course? 
• How do I manually add students to my Blackboard course? 
• How can I merge two Balckboard courses into one? 

Unforatuntely, this Wiki is only in German so far.Therefore, please reach out to the teaching planning team of the Institute at lehresoz@polsoz.fu-berlin.de if you need help.

In the wiki, you also find the contact information for support.

In addition to the contact information provided on the IT service portal, you can also reach them as follows:
