     No, it is not a "Gotcha" for using MySQL and Base. It may be a 
"Gotcha" because of how you have created the database. Creating a 
database is somewhat like building a house: you need to have planned out 
what you want first and how to create it. This does take time, but it is 
well worth it. Some to several problems that you have had is because 
there seems to be no well thought out plan/design for the database from 
the beginning. Part of this involves normalizing your tables. As stated, 
70 fields in one table is very often an indication that the table is not 
normalized. This can lead to errors in entered data.
     The Primary-Foreign key pairs in MySQL are defined in views, 
queries, and forms. All of these are written to the Base field (.odb). 
What I think may work is to create a view that uses the essential fields 
from your 'Member' table and the needed fields from the 'eMail' table. 
Then you could create a form for this view that has the things you want.
