- How are e-mail communication and e-mail relationships unique as compared to face-to-face interactions?
It seems to me this depends on the tendencies and motivations of the participants. Newcomers (and even "seasoned veterans") are often surprised at feeling a sense of openness and candor in this electronic world. It seems to me people are often more willing to discuss personal matters online than in person.

- What unique opportunities for relationships and groups does the internet offer?
I've seen several occasions in which people have met online and pursued a "real life" (rl) relationship. These relationships are sometimes romantic, sometimes platonic, in nature. Obviously, geography is not the barrier it formerly was. The U.S. has been called a "melting pot;" perhaps the internet contributes to a global "melting pot."
In terms of groups, I think specifically of support groups. I've encountered quite a few people online who find solace and comfort from the online community--there are many sympathetic ears. With support groups, participants need not leave their home, or wait for a scheduled meeting--a support group is available, via their monitor, at any time.

- Are there gender differences in how people use and behave on the internet?
This brings to mind an interesting/amusing story I read some time ago. A female was annoyed at the unrelenting approaches of males online. She changed her online name to a male name and the nuisances stopped. But she found it was much more difficult to obtain online help--men didn't exhibit the same willingness to help another man they had shown a woman. Some might call it chivalry, I suppose!
