You should, wherever possible, record your classes in Adobe Connect so that students can later look back at these.
These recordings should then be made available to students - ideally in the appropriate module in Blackboard.
It may be useful to include a slide in your presentation files to remind yourself to record your classes in Adobe Connect.
You can also encourage students to remind you to record your classes at the beginning of each lecture.
