Ultimate Membership Pro

Last week I asked a followup question about Ultimate Membership Pro, but did not hear back. I am interested in becoming a customer but have other questions.

  1. Are all fields in the membership searchable by the members?
  2. Can I use a different theme other than yours?
  3. Do you support 2Way Videochat plugin, or CometChat plugin?
  4. What is your reputation for tech support response?
