[support] Realtor Web Site

[MichelleX]

Hey guys -

I know Realtor type web sites have been created using Drupal, but my 
client has inquired about some things I'm having difficulty finding 
answers to on the Drupal site.
So, I'm hoping someone here may know the answers.

- Is it possible to have a custom IDX option?
- Is it possible for users to save searches and have them emailed to them?

Any ideas are greatly appreciated.

Thanks,
Michelle
