I have started extending the user registeration module to include more stuff like state, country, etc etc.

But without any documentation, I am wondering which DB table should I add these properties to?

I noticed there is a table called "members", but the two existing user properties in the profile are serialized in the profile table.

So my question is, Should I add these fields to the  members table and if not, which table then?

If nyone has already done this, can you give guidance?

Any guidance  from MS team will help.

Thanks
