Can you show me an example of where this is happening?
One problem I am trying to work out is that there are multiple domain names for the site (in-gender.com and ingender.com). Either one works, HOWEVER the site only recognizes you as being logged in to one of them.
For example, if I log in using in-gender.com, and try to click on a link that uses ingender.com without the hyphen, it may not work because the system thinks I'm not logged in to view that post. So if a link isn't working you might try adding or removing the hyphen in the link.
Sorry about the issue, this is somethign I've been working on but it's a hard one to fix -- unfortunately it was written poorly in the first place (not by me!)
