One more thing: if you leave a note on any kind of discussion page it's always helpful to sign your post with four tildes (~~~~), which is automatically converted to your username and the date and time. Don't do this in articles themselves though as they are not 'owned' by any particular contributor.
If you have any questions, see help, leave a question at the help desk, or feel free to drop me a line on my talk page.
The developer team at Wikimedia is making some changes to how accounts work, as part of our on-going efforts to provide new and better tools for our users like cross-wiki notifications. These changes will mean you have the same account name everywhere. This will let us give you new features that will help you edit and discuss better, and allow more flexible user permissions for tools. One of the side-effects of this is that user accounts will now have to be unique across all 900 Wikimedia wikis. See the announcement for more information.
Unfortunately, your account clashes with another account also called Jordy. To make sure that both of you can use all Wikimedia projects in future, we have reserved the name Jordy~enwiki that only you will have. If you like it, you don't have to do anything. If you do not like it, you can pick out a different name. If you think you might own all of the accounts with this name and this message is in error, please visit Special:MergeAccount to check and attach all of your accounts to prevent them from being renamed.
Your account will still work as before, and you will be credited for all your edits made so far, but you will have to use the new account name when you log in.
