The idea behind all this is the webapp allowing realize some operations even 
without the user being registered and logged, to make it easier for example 
do a donation or create a look-for-volunteers notice.


The webapp is sending always the same email when the email address is not 
registered yet. The email is registered at E1_Entities.  The webapp sends:


   Your email has been used to create or update a notice at GNU Herds.

   Follow the below link to confirm. That link will expire in 48 hours.

     http://../entity?action=verify&address@hidden&magic=bc72ae13f414

   If you have not asked for it, ignore this email.

   To avoid 'Spam' you can only get this email at the most once each 48
   hours. If this email is Spam for you, please let it knows to
   association AT gnuherds.org


Note: If the created EntityId is deleted, due to lack of confirmation, then 
any operation, being subscription, donation, etc. will be deleted.




Operation catalog (could be incomplete)
=================

For the case in which the email is already registered but the user did not log 
in to carry out the operation, the 'magic' number used to confirm the 
operation have to be recordered at the data base register which is being set 
on hold, along with its date which will be used by the cron job which will 
delete old non-confirmed registers:


 Register entity: Person, Company or non-profit Organization.
 ---------------

    E1_WantEmail  -->  E1_Email

    E1_RegisterMagic
    E1_RegisterMagicExpire



 Create new notice
 -----------------

    * job-offer creation
        Note: Right now, requires the user to be logged in, so
              there is no problem in the case we are working out now.

    * donation-pledge-group creation

    * look-for-volunteers notice creation


  We need to add the below fields at J1_JobOffers:

    J1_CreateMagic
    J1_CreateMagicExpire



 Subscribe to notice
 -------------------

    * subscription to job-offers
        Note: Right now, requires the user to be logged in.

    * subscription to donation-pledge-group.
        Note: It allows subscription without being logged in.

    * There is not support to subscription to look-for-volunteers
      notices.  We just shows the email and interested people can
      get in contact with such email address.


  We need to add the below fields at R0_Qualifications2JobOffersJoins:

    R0_SubscriptionMagic
    R0_SubscriptionMagicExpire



 Donate to notice
 ----------------

    * donation to job-offer (Is it convenient add this feature later?)

    * donation to donation-pledge-group

    * donation to look-for-volunteers notice (Not yet. It is delayed.)


  We need to add the below fields at R1_Donations2JobOffersJoins:

    R1_DonationMagic
    R1_DonationMagicExpire




Note: The user have to be logged in to be able to cancel a donation, or to 
delete a notice. So there is no problem.


As usual, flames, disagreement, correction, comments, etc. are not only 
welcome but needed!
