A good plugin which alot of users would benefit greatly from would be one that creates certain restrictions to the registration.
these could include:
1) certain domain names (eg @hotmail.com emails only)
- possibility to create several domains that email addresses at registration will be limited to (eg @hotmail.com and @hotmail.co.uk)
2) certain domain suffixes (eg .edu etc)
i know to do this would be quite easy to someone knowing what they are doing. Does anyone think they can do this or have the time to do this? cheers:)
