Hello/namaste,
Another Marsdenite- an absolute novice /amateur with regard to autograph.
My areas of teaching extend from Biology/junior science to Maths A/junior maths, and I'm always like most teachers on the look out for new/latest resources that will add that extra 'oomph' to the lesson.
I have been exploring the various site links along with the autograph applications available.  The time spent on this has been worth my while- specially at this time of the year when we are on our way to planning & improving curriculum delivery methods for next year.
Explore/enjoy/pass the word!!
