Mohammad,

Yes, I have played with this - but I thought it increments in a session but 
the number is saved and continues, is not reset on reload, as the document 
implies. I need to recheck this.

I played with it for version control, I save the change count when I stamp 
it with a new version number. Thus I could determine if the tiddler has 
changed since the last version stamp.

Actually this is a timely reminder, as this will help me with a solution I 
may be able to develop professionally for a client. My first ever 
possibility of being paid to play with TiddlyWiki.

Its a more advanced method of detecting is something was modified recently. 

I imagine it is change count that haschanged[] uses.

Regards
Tony
