    We have to call it regrouping not trading these days so could we have this poster with regrouping replacing the trading word?

    Hello Lesley,

    You are so right! Thanks for alerting us, ‘regrouping’ is the preferred term and we have updated the resource to reflect this.

    If there is anything else I can assist you with, please don’t hesitate to contact me.
