Unfortunately, some accounts are currently not unique across all our wikis, but instead clash with other users who have the same account name. To make sure that all of these users can use Wikimedia's wikis in future, we will be renaming a number of accounts to have "~” and the name of their wiki added to the end of their accounts' name. This change will take place on or around 27 May. For example, a user called “Example” on the Swedish Wiktionary who will be renamed would become “Example~svwiktionary”.
Why did you choose to insert the character "~"? Many keyboards do not have such a key. Cruccone
