The Society’s Community has a powerful search tool. Click on the spyglass icon in the top right of the screen and enter the text you would like to look for. You will then be able to sort the matches by relevance, date, or how well it was liked.
If you need more specific results, there is an advanced search option. Click on the search icon, then click ‘options’ to filter results by category, user, tags and many other criteria.
