You can create a sandbox by going to your userpage User:Joahkin and add any pagename you wish as the suffix, ie User:Joahkin/Stuff. The name of the subpage is really just a note to yourself and "sandbox" is the generic name for it, you're free to name your subpages whatever you like, though.

I'm not sure if you're able to delete or rename your sandboxes as a non-moderator - I  believe non-moderators can rename regular non-locked pages so you should be able to, so if so that option would be under the "Edit" dropdown of your sandbox page  User:Joahkin/sandbox  in the upper right hand corner (though we ask that if you rename that you do so without a redirect keep our redirects neat and tidy). If you don't have that option, just let us know what you want it to be renamed (or if you want one deleted).

Sandboxes act like any other page on the wiki, but what makes them unique is that they don't count towards the Wiki's page count, they aren't linked anywhere which means you can collect useful files or blocks or text, or build up pages so they're complete before they go live to avoid swamping Special:WikiActivity and the live page's history with many small concurrent edits, and no other editor can edit them (per our rules) which means you can edit your sandbox as much as you want without risking editing conflicts with other editors (which will undo your changes).

Hope this helps!
