Users whose accounts are blocked by us for certain reasons need an information directly after logging in about
1. the fact, that the account is blocked (access to account must be possible at any time to give the possibility to pay online) and
2. the reason why the account is blocked (fee too high, media overdue, please contact library etc.).
Different values should generate different messages and it must be possible to "connect" messages coming from third party LMS to certain text messages.
