#echinopsis #whiteflowers #whiteechinopsis Hash tags are a great way to group photos by topic and/or subject matter. Anyone can start a hashtag or add to one. Simply place a # ahead of any word or phrase you want to create or add to. Hashtags can be fun!! 😊 But mainly tags are useful when doing a search for something, including admin who use them to compile posts/collages as part of the regular challenges.
