Is it possible to attach a membership number field inside the registration form to a list of membership numbers, say an excel document or any type of list doument, and auto approve members throught that, so if a membership number in the registration field matches a membership number in the document then it approves them automatically, to save time, etc...

Any help on this subject would be grateful, even if someone is willing to program something for this for a price, state your price or send me a private message.

Thanks in advance
