Before I start, I have read all of the warnings about modifying core files. However,  The joins that DNN uses for users, profiles etc are way too expensive for the size of application I am writing.  Instead I am putting the profile in the user table, using a bitmapped integer for roles ( this gives you up to 31 roles) and all the other db stuff a dba would do :).  To that end I am rewriting the business and data layers for registration and profiles.

I have been thru most of the docs and what I still cannot figure out is:

1)  how to programmatically get the current portalID.  I can't seem to find where the PortalID property of the userInfo class is set during registration.  Its default is Null.NullIteger which is great for 1 portal with an id of 0, but as I add portals that won't be so convenient. ( I could get the portalID by portal name, but how do I get the current portal name?)

2) Same as above for AffiliateID.

2) find the tabid of a given page (it would be great if this was under the Page Details of Page Management of a given page/tab.  Right now I am just looking at the link when a page comes up and using that.)

3) map to a folder that a user uploads an image to. (currently I am just storing user profile images in the database as a workaround).

4) Does isHydrated mean a class's instance has been filled with data?

If this is all in a document somewhere could someone point me to it?

Thanks,
