After recent BotNet attacks on GeekShed and other IRC networks, lessons have been learned and measures have been put in place to mitigate the effects of future attacks. One such mitigation method is validation of e-mail addresses. When you register a new nickname in the future, you will be sent an e-mail to ensure that it is correct. This e-mail will contain all the instructions you need to activate the nickname. Note that this does not apply to grouped nicknames and most users will not require more than 1 nickname group. See for help with grouping. Any questions, ask in #help.
