A user page is a page about a wiki user; someone who registered on the wiki, and is a contributor. You can find your user page here.
If you have registered, you can create your own user page. Your user page is linked in the top left. More importantly, others will see links to your user page from various places which assist wiki collaboration. This includes the "Recent Changes" and "page history" displays (See Help:Tracking Changes). You can also link to your user page within text of a wiki page, which is mainly useful on talk pages when you sign your name.
What to put on your user page
User pages are just as flexible as any other wiki page, and it's a page all about you, so generally people will leave you to freely write your user page in whatever format you like. It's a feature to help other people know who you are, and to bring the online community closer together. Think of it as a “profile” page. You might like to mention where you are from and what your job is. You can also state what your main areas of interest are in relation to Scratch, and describe contributions you have made or areas where you are interested in contributing.
User sandbox / development area
You can use your user page as a sandbox. An area for developing ideas without cluttering the main namespace (see Help:Namespaces). If subpages are enabled (see Help:Subpages), you may find them useful for creating sub pages under your user page. However you should avoid expending too much effort within your own area of the wiki. Be bold! Edit the main wiki articles! If your wiki has a shared Sandbox page, you can also use it for quick (non-permanent) wiki experimentation.
Other people's user pages
As mentioned above, you will see links to other people's user pages, in various places throughout the wiki. They will most likely appear on a page's talk page. If at any time you discover a link to a userpage on a page that is completely irrelvant to the article, either remove it or if unable to, ask another user to do so for you.
When viewing another person's user page, an additional link “user contributions" appears in the “tools” of the sidebar. This takes you to a list of all of this user's wiki edits. Use this to get an idea of how prolific a contributor somebody is, or to track down edits made by a user who is causing trouble/making bad wiki edits.
Editing someone else's page
- Main page: Scratch Wiki:Userspace
Editing someone else's userpage is not allowed except when removing content that obviously violates the Community Guidelines or in the case where the owner has given you permission to edit.
User talk pages
- Main page: Help:Talk Page#User talk pages
Every user page has an associated talk page; a "user talk page". This is a special kind of talk page, for leaving messages directed at a particular user.
Link to a user page
To create a link to the user page of the user that clicks that link, use Special:MyPage.
You can create pages that you do not want anybody else to edit in your Sandbox. However, if you give them permission to edit, or your userspace page breaks formatting or is inappropriate, then another person can edit your userspace.. This would be the place to put your
The link to pages in your user namespace would start with [[User:YOURUSERNAMEHERE/PAGETITLEHERE]].
