Hello once again dear language enthusiasts,

Today I'd like to suggest another useful website MindMeister which you or your students can create mind maps on whatever topic they wish or a complex concepts that they challange to understand to reduce the incomprehenbility.

Mind maps are always useful and rather than drawing them on the paper, creating these maps digitally and adding colorful details on them are much more beneficial and helpful for one's learning and even teaching process, I guess. Creating these maps also enables learner to remember topics easier.

You can go to the link and may be think of a concept that you hardly understand and create a useful mind map involving certain key concepts about the idea you're trying to grasp. Then check if you get the idea better...
