That thread didn't come out quite the way I had planned it. I had actually wanted to offer some sage advice about the advisibility of keeping track of the workshops you attend.
If you haven't done so already, keep a list of all the workshops you attend including dates, times, and if applicable - course numbers.
In my district, teachers are required to submit this information to administration at the end of the year - and it's always a pain to have to look up this information several months after you attended the workshop.
Some teachers also include information about workshops they've attended on their resume or in their professional portfolio.
You never know when this information will be handy.
