It would be better if the Text editor suggests the correct words as like displaying the incorrect word.

Yes that would be better. It would also be better if we did not get that popup box everytime we paste into a forum message. It would also help if the A, PRE and other tags were not removed when we edit a message.

Look around in these forums; you will find these and many other things that have already been mentioned and that they are working on. As far as I understand things, we were supposed to have gotten an improved editor by now. Note that the software developers of the editor currently being used here are from another organization; you will see the details of that when you find the other threads.  It is my understanding that a new editor is being tested so I assume it is more work than they hoped for to get it working.

In a few months, we will have an all new site. Mahesh says that it will do so much for us that it will even drink our beer for us. So we have to wait for many of the improvements; they are investing most of their time into developing the new software.
