Yes, absolutely! We require registration to use some of the advance features that we feel may have potential for abuse ie. ability to IM other users, but we'll always have a FREE basic registered membership for those kinds of reasons.
We plan to have paid features for those that wish to support our project, but we'll always have a FREE basic membership available.
Of course, you don't have to register to utilize our directory web site, but rather only for some advanced features and benefits.
