This is an umbrella issue encompassing the various IZ issues.

Previously, Helm and IZ were separate systems with separate accounts.  Now, IZ
is "linked" to SourceCast.  Whereas before a user logged into IZ separately from
Helm, now logging into SourceCast automatically logs the user into IZ.  In
addition, the IZ account will show the user's email address as
"username@netbeans.org", which is simply an alias to the corresponding
SourceCast account (which forwards email on to the username designated in the
SourceCast account).  The possible problems with this are as follows:

1) Users who had IZ accounts but not Helm accounts before the migration now have
no SC accounts, and cannot log into their IZ accounts (as logging into IZ
separately has been disabled).

2) Users who had IZ accounts and also Helm accounts, but using different email
addresses and/or passwords, will not be able to log in in the manner to which
they are accustomed.

3) Users may have multiple IZ accounts now, causing confusion when someone
assigns an issue to one of their 'other' accounts.

4) Users may be confused by the appearance of the 'username@netbeans.org'
address when they use IZ.

5) Users will no longer be able to register for an IZ account from the link on
the Bugs page.

6) Users may have different permissions than the ones they used to have.

Here is what we need to do to resolve this:

1) Remove outdated and incorrect IZ accounts.

2) Create new IZ and/or SC accounts where needed, and verify permissions.

3) Change issues (owner, cc:, etc.) to reflect new accounts.

4) Write a document to educate users about new process.

5) Remove outdated link on bugs page.

6) Verify that new accounts are being created with correct permissions.
