It's pretty easy to just tag things as just #art or #photo or #writing
but if you're like me who likes to share other people's work, posts, or just like to post a lot yourself, having a custom tag is very nice, especially if you pin it!
For example, my tags for my own art work are #MintyWyvern Art and #MintyWyvern doodles ! I have those pinned on my profile so people can look at just my art only if they click on my page
The way to do is is to first, have something on your page already using your custom tag, next go to the cog wheel on your profile
It's the middle cog button right after edit profile. you then scroll down to the pinned tag settings and from there pin which tags you want people to click on.
and voila!! very easy and helpful!
Edit:
As another incentive to use pinned tags, when you make a new post, you get a menu of all your pinned tags as well as any recently used tags!
