It seems there were a couple of problems with account creation on AnOtherWiki. While you could sign up using the login/create account link in the upper right, the link to create an account under the Help:Registration page did not work properly. This has now been corrected.
Further, it appears that I set up the DNSBLs that AnOtherWiki uses to be a bit too strict. As a result, some Comcast users were incorrectly being blocked due to their presence on the Policy Block List of spamhaus.org. I have now stopped using zen.spamhaus.org, which incorporates the Policy Block List, and am using the Spam Block List and Exploit Block List individually. Other users besides Comcast may have been affected, it was just reported by someone using Comcast. If you tried signing up before and were told you were using an open proxy when you weren’t, try again. If you’re still having trouble, send me an email (jarandhel at gmail dot com) with your IP address and I’ll look into it.
Finally, I’ve changed the captcha questions to try to make things a little easier for folks new to the community. If you’re still having trouble with them, or would like to suggest additional general-knowledge otherkin questions that could be used as captchas, please email me at the address above.
